Queen and Nimzo Indians tend to be very good. Moves are usually natural without having to play passive symmetrical crap, though there's room for transposition like anything else. Leningrad Dutch mainlines are easy to remember, but still has plenty of only moves and you need to be versed in anti-Dutches too, such as the Manhattan Gambit (if white offers an h3 pawn after sacking on g4 don't fall for it and play ...g3 usually)
I wouldn't recommend the Dutch until you're maybe 1500-1600 however.
This is interesting pfran. Before joining chess.com I used to play against Chessmaster software and only and I always used to play 1.d4 2.c4 . Started playing against 1400 rated personality and within 8 monthas I was defeating 2200 rated personality there. That program never ever employed King's Indian against my Queen's Gambit.
So when I joined chess.com I used to get sick when somebody play KID. :)
I am still a novice in chess but I have read more often than not that KID is the best defense in QGD.
