Which format do you prefer to play in otb.

Me rapid-not too short not too long, and classical sometimes

90 minutes for 40 moves, then 30, 30 seconds per move from the start. But 90+30 for the whole game is also OK.

Same as mkubecek. 90/40 + 30, then 30+30.

Which happens to be the time control for the dutch chess federation competition.
