I like this position for white.
But ...
on my database search I read that instead of 10. f3, Nf3 should be better, but I don't really like it, I think black can equalise more easily.
I wouldn't know how black can equalise there. The simple development with 10.Nf3 is very strong and I think white is better in most variations. David Vigorito has some good discussion on the topic in his Callenging the Nimzo-Indian book, where he analyzes the game Xu Jun - Wang Rui (see below). He has one subline with an early h6+g5 for black, where he thinks black might be fine, but I believe that due to the shakiness of black's kingside white is pretty much winning there, too, and my analyses back that up and I'm just waiting for the someone to play b5 against me. If you play Qc2 as white, then that book is well worth getting.
Xu Jun (2626) - Wang Rui (2481) [E32]
