Vaporeon as it has the best moveset and stats of the 3 Flareon has the worst stats out of all of them as it is a physical attacker when its stab is special. Jolteon has a moveset with alot of physical moves when its attack stat is 65 and only has dark type special coverage in bite While vaporeon is a bulky special sweeper with a good moveset I suggest this set for in game- Aurora beam->Ice beam-good against erika and lance Water gun->surf-good against blaine giovanni and bruno's onixs Bite-good against sabrina and agatha Acid armor-makes it super unkillable
