Gonna risk it and say it's either DP or BW1
Not so sure about DP since I really liked it when it came out, the new internet features completely changed the pokemon experience worldwide, also, the split bewteen special and physical not being type exclusive anymore was great, lot to do post game, or at least, lots or legends to catch, even if it felt kind of idiotic and the feel was comfy as hell, I was mad about secret bases being gone though (Underground was shit in comparison) .
Gues BW were the worst, too bad because I think they had the BEST story overall, but I feel they added a FUCKTON of new pokémon, no new evoltions and the starters were IMO the most boring ones in contrast with the tyings they had on DP, also, they took out shit lke the pokemon following you, secret bases, contests, or the pokéathlon, the dance was completely irrelevant and some of the sprite animations for the pokemon were really odd.
So, yeah, I gotta go with BW1, specially the post-game was empty as shit and there was NO WAY of rebattling any trainer other than the E4 or rivals.
BW2, though, were some of the best, IF NOT the best game so far with content alone.
