Umbreon and Vaporeon are basically incapable of Offense and offensive Sylveon sets compete with Gardevoir, who keeps it out of RU with a better type, better speed, and better attack. In UU there's Hatterene, which is slower but fits on TR teams and has Magic Bounce, and in OU it's competing with Lele and Fini and it is not winning.
Jolteon competes with Thundurus, Raikou, and Koko, all of whom are just straight up better than it and it literally doesn't have enough moves to run a specs set.
Leafeon's stats are usable but not great but its main issue is that it doesn't get any fucking moves. Just Leafblade, X-Scissor, and Knock Off. There are 200 better Knock Off users.
Flareon and Glaceon are shit and unless they reallocate stats, they always will be
