I prefure the MFFB stick simply because its accurate, well built, comfortable, and it has FFB, but I don't use it in IL2, I alt tab too much and IL2 drops the FFB when you alt tab out of the game. I do use FFB in ROF though, and hope to in COD.
No experience with freetrack but a few dogz have and still do.
Perfessor, mayhem, and jedti used too.
