If you mean the anime, I still like that early episode with the two metapods trying to out-harden each other.
If you mean battle style, I prefer 6v6 singles, Anything Goes, the more laid back and casual the better. Especially if it's just our two in-game teams and HM users duking it out, those are the best.
