What is your favorite opening as white or black?

I know many of you found my previous work controversial, so I changed it to this.

white-grand prix attack

black-kings indian defense

uh wrong club?

BLACK- KID OR PIRC. WHITE-d4

Accelerated London for white, If I'm playing black, then the Caro-Kann for e4 or f3 or the Slav for d4. 

English if I am white with double fiancetto bishops, and for black, King's Indian because you get such a major attack on the kingside

I would say Italian Game for White with Bc4 because it attacks the f7 pawn and leading to Evans Gambit and other agressive and great openings. For black I would say The Giocoo piano game if there is the Italian Game because there can be some advanteges there. So both are good openings..
