It may be too late, now, sorry, but I own both the Ferrari and the Interact wheels, and my preference goes to the Ferrari one, especially for F 355!
In this game, you can use the paddles to brake/accelerate and the levers to shift up/down. This may seem weird, but that is impossible with the Interact one, on which paddles and levers have the same functions...
I also tried a Saturn MadCatz wheel, for almost the same result...
I do not know the original Sega wheel, nor the MC one, which looks exactly like the Saturn model. I know there is an other MadCatz model, the MC2, which is apparently really nice, but I did not try it either. You can find it here:

Hope it helps!
