Honestly my moveset on Jolteon prevents it from being a sweeper so It's really used to take out anything that's a huge threat which seems to consist of pokemon like Suicune, Mega Aerodactyl and Salamence which I see often in UU.

I mean for what he's using it for Jolt would be better. It's faster than Heliolisk and it's Special is prett much the same. It's seems to be for dealing with thigns that are weak to electric and that the surperior coverage on Helio isn't needed. Once again... preference is just as important as how actually good a mon is. Each has their advatges and for what it's sound like it's being used for Jolt has an edge.

The main reason I use Jolteon over Heliolisk is simply that it's my favourite Electric type
