Well? Title kind of sums it up.
It's hard to define which you like since I'm sure there will be some you like in Black over the White counterparts while there will be some you like in White etc... but I guess a way to vote would be majority rules (if like 7 in Black and 5 in White, vote Black).
You can vote based on any criteria for why you "like" a Pokemon, of course, but personally I'm just interested in Pokemon people would actually consider using.
If you could tally up how many you like from each in your posts that would be extra helpful (ex: Black: 10, White: 6), and extra-extra helpful would be naming the Pokemon.
