Hardest/Easiest Gym Leader so far?

[AndrewErblak]

Hmm...

Hardest: Until I worked out a pattern, the psychic leader Radomus, he just kept using Chess Moves on me and when I had a few fire and flying types, that sucked, he never once got Trick Room up though. Charlotte was hard until I found out Rain Dance ruins her effectively. I did have some issues with Noel, but TerraTwig just kinda made them go away. But then there was Shade... and his Chandelure... didn't have anything faster then it, so I had to resort to Noble Roar from Brave Heart to cripple it, although I do feel like I've done that a lot before... Serra was hard couse of 2 Pokemon, Cloyster and Lapras, everything else I was fine with except those two.

Easiest: Flobot, Luna or Samson, Torterra just destroyed them all with Curse/Seed/Eq/Razor Leaf, 1st shot all 3.(Please note I did get a 4x attack Razor Leaf crit the Cradily.)

So in order from hardest to easiest from the listed above:

Radomus, Shade, Serra, Charlotte, Noel, (skip a fair few leaders), Shelly, Aya, Flobot, Luna then Samson

*Edit* Aya wasn't that hard, more of the same, know what's gonna kill you then cripple it with BraveHeart, it works, well for me anyway.

Shelly was kinda meh, Emolga was clutch for me in that battle, having a Growlithe and a Pyroar helped a lot, just same, cripple then STAB kill after a few work ups.

The easiest for me were the fire gym, Aya (ep 12), and Flobot

Fire Gym: My semi-ev trained Camerupt (with focus band), swept her entire team. I was stunned at how quickly it went.

Aya: I got my sandslash and camerupt earthquake and they just steamrolled almost her entire team, though they kept KOing my other mon so that it looked like the two of them were the three stooges.

Flobot: It wasn't too hard thanks to my infernape and beautifly.

Hardest one for me were Radomus, Julia, and maybe Corey and Shade.

Julia: None of my mon had ground attacks and the ones I had been levelling up were weak to electricity. My pachirisu was a boss though, she used bide and endured both voltorbs exploding and just rammed it up emolga's butt. The rest was trying to keep my monferno alive by using my other mon as shields.

Corey: like Julia I didn't have any psychic mon/attacks and my only ground one was my Arbok's mudshot. It was the poison spikes that were a pain in the butt.

Shade: Despite levelling up my best mon to nearly the level cap I couldn't beat him so I had to train up a Raticate ghostbuster specifically for that fight, she took out over half shade's team.

Radomus: If it wasn't Gardevoir it was slowking or Metagross killing my Mawile and other key mon. I had to train up a boufalant since it knew Megahorn and could tank their shots. The key moment was when my Mawile and Boufalant had their big attacks aimed at slowking, by either the RNG gods smiling on me or Radomus' error, he sent out Gardevoir. Both shots took her to under half health and I just thwomped her before she could get a calm mind or moonblast off. I should not have won that one.

I've been training up mon for future gym fights but even with them EV trained half of them will probably prove useless knowing Ame and reborn. The fights have been hard but they've almost always been memorable and provide plenty of moments of awesome for my mon.

In all honesty, Aya was the only leader that legitimately gave me trouble. Maybe it was just my team, but I actually swept through most of the other leaders on the first or second try.

Julia: She was very kind in powering up my lightning rod Electrike for me.

Florina: Kriketune (probably misspelled) set up and destroyed everything.

Corey: I don't remember what I did here exactly, but it swept through quickly and I moved on.

Kiki: Gothita and Noibat won this one for me, along side my Greninja who baited her into using moves like HJK, then used lick to turn into a ghost.

Aya: I ended up completely revamping my team. I trained a Flygon, Sandslash, Klink, Magneton, and Shedinja just to make sure that i could beat her.

Serra: I fought her in Episode 12, so she wasn't as difficult anymore, so my Pyroar and Magneton plowed on through.

Noel: I had a Scrafty which decimated. I also had Magneton and Manectric to kill the birds and Clefable.

Radomus: I trained up some new Pokemon here, but that was simply because I knew I'd be leaving the area for a while. I grabbed Aggron, Gardevoir, Archeops, and Mawile here. When I went into the gym, it was a cake walk.

Luna: Gardevoir, Scrafty, and Pyroar swooped in from above and 6-0ed her.

Samson: At this point I did some training and rotating out because 5/6 of my team were weak to fighting types. I trained Archeops and grabbed Hawlucha. These two combined with Gardevoir won it easily.

Charlotte: After fights that are meant to force you to think, I was kinda disappointed in this one. Rain Dance+Archeops and Flygon spamming Rock Slide kills everything.

It always depends on your team, but.... I always have no issues and issues on repeat playthroughs with these two....

Florinia is the hardest

Julia Easiest

[Revengercm]

easiest: the fighting gym

hardest: second time poison gym. Idk how that Dragalge (oh howerver you write it) one hits me everything.

[ShadowDefender]

Easiest: Shelley, even after making her doubles. Crobat+Growlithe=easy win. Of course, pre episode 12 Kiki with a Crobat. Acro sweep all day.

Hardest: Noel. That ******* Proygon-Z man.

[Dei]

The bug gym. That probably has a lot to do with the fact that my starter is a fire type and my other two Pokemon were flying types. xD (At the time my Pokemon were Delphox, Noivern/Noibat, and shiny Pidgeot)

Well upto now I faced upto Luna and just clearing things before Agate Gate. I am a recent player for this game so i will rank all these 9 gym leaders based on my team on how i faced them. 
Easiest: 
Luna : may be because of my team it's way more easier to counter her. I didn't even change her filed My team is staced with Heracross, Bewear and Primarina cutting Luna easily down.
Shade: It's obvious the most mysterious character is actually pretty easiest gym till now. Though his gengar(corey) has hypnosis, just avoiding it's accuracy is enough. By that time i have a phantump, and a stunky to deal with shade better.
Serra: Special team and serra goes brr.... Seriously with all the special attackers with me by that time i took down serra with ease. I have a simisear who whacked through half of her team, primarina who supported and bulked in this process and a swalot with toxic that took hits and stalled everything against her.
Moderate:
Julia: may be because of my starter(popplio) i faced a bit against julia. I need to take care of her speed especially not going to set her oricorio a tailwind. But apart from that the weak charge beams didn't do me much yet i need to tactically think of her so yeah julia is moderate for me.
Randomus: The trickster is either easy to break or a menance there is no inbetween for him. I faced him in 3 play throughs the first two where i got demolished and the third where i demolished him. The main thing is which position pieces you need to keep your pokemon. My palossand, trevenant and queen stunktank did a lot of help in my 3rd playthrough. So yeah basically good positions clears randomus. else he is a menance.
Shelly: So, if it's not for primarina i may have suffered at her field and bugs, but thanks to primarina and it's sparkling aria. I didn't let her anorith tear against me. With help of my bewear's thunder punch i stopped the grass hazard pokemon yanmega or araquanid. Shelly i played 3 playthroughs because understanding her field is really tough but as i progress my team actually stepped over this hazard with ease luckily.
Aya: So, basically all the three double battlers till now are moderate for my team. For aya I put a klang in my team to move against her poison weaknesses. Primarina to eliminate the ground move pokemon like nidoking and talonflame for the extra speed. So basically i stacked a team against her (with swalot to take hits). and slowly cleared aya but honorable mention if not for my timely switches aya made me struggle for sure.
Hard:
Florina: Damn that ferroseed and cradily. Florina being a pokemon leader with a type of many weaknesses managed me to bite my nails. Her field is a problem for me making things difficult for flying and poison typings. The fire type pansear didn't work a lot and taken down easily so i really struggled to get past florinia. I need to make huge changes from my julia's team to florinia's team and need to do lot of  mind map on assuming when that damn cradily would come out.
Noel: Absolute menance. The magic guard clefable is a nightmare for sure and his remaining normal types are not to downgrade. By this time i don't have a heracross, so my fighting warrior was bewear. and I used palossand and trevenant to miss his attacks but yet i struggled a lot to go through his team, may be because fo movepool. I struggled like hell and needed to play nearly 6 playthroughs to beat him. Noel went straight up demolishing me with his pokemon. So he gave me the hardest time till date.

For corey i would say he is easy for me and kiki gave a moderate time because i thought of a flying option against her and took 3 flying types which is actually dumb to do with her field but i slowly cracked it with help of my primarina and palossand. 

So now i am at agate gate and most of the pokemon i use are as mentioned above. I generally rotate between them (regently caught and aron and made it aggron so include aggron too). Hence you can give suggestions on which other gym leaders may give hard time to me in future with my team, and what's better to catch before i reach agate city (i think i need a psychic type for sure but which one should i catch you can suggest me for sure).
