I know there was one guy somewhere in the Emerald Battle Frontier who could point out your highest IV stat and give an indication on how good it was, but that was about it as far as I know.
I think I mostly used Slowbro, Exeggutor, Jynx, Gengar, Alakazam, Aerodactyl and Dodrio. (Ok, latter two are actually physical for variation.) It wasn't really what you could actually call competitively, since I only battled my brother, a friend and Battle Frontier NPCs with them. On Showdown, I tend to use some more useful Pokémon as well, but I just can't bring myself to train legendaries or Pokémon I don't like in-game.
