I hated reborn for its gym leaders having a full team at the soft level cap with the extra field effect that boosted them in way that felt like hackers in other pvp games. Then when I played rejuvenation, I noticed a ton of improvements like difficulty choices (including mentioning which difficulty was on par with reborn), an audino trainer you could rematch infinitely (despite not requiring it nearly as much as reborn), and best of all my rock type didn't start disobeying me mid battle against the ice gym leader. That may have been the one time I ever hit the cap in rejuvenation, but I might actually go back for my 5th badge in reborn if they changed to a hard cap.
