Funny, I have exactly the opposite experience. I generally play racing sims on a FF wheel, and when I try them on a gamepad, I suck so bad, it's not even funny.
The thing about wheels is they are no where near actual strength. I read an interview with one of the engineers on the original Sidewinder FF wheel team at one point a long time ago (wish I could find that article), but he made a comment that the forces represented by the wheel, at default are WELL below the actual forces a real car would generate. Powerslide has an option to adjust the amount of force generated. You can dial it from -10 (no force) to 0 (normal force), to +10 (about 4 times the FF normal forces) and even that, according to the powerslide docs, is about 1/10'th the actual force you'd feel driving.
I crank powerslide to 10 and play for about 10 minutes and my arms ache, but it's a good ache!
What I've noticed is that people tend to try to use a FF wheel like an arcade control, instead of a real car wheel, and in any decent sim, that'll have you all over the road in no time.
But, like I said, I stink with the game pads, so....
As far as the wheels go, I've had an original Sidewinder, and a logitech, both older models. I'm in the market for a new one, but I'm seriously considering a driving cab, so if I go that route, I may be looking at one of those high end models that uses hydraulics or some wacky stuff like that!
And that VR projection dome system looks utterly fantastic
