Forza Motorsport 3 vs Need For Speed Shift?

Which has better driving physics, tuning, customization, painting options, tracks, cars, AI (I mean opponents in a real race, not monster truck AIs), which graphics look more like REAL life, and online.Forza Motorsport 3 vs Need For Speed Shift?
Forza Motorsport, didn't you saw the trailers?
I have Forza and have played need for speed shift.

Forza 3 is much more realistic, and the customization options are amazing.

It has many live features. I don't really like need for speed shift.Forza Motorsport 3 vs Need For Speed Shift?
forza is a sim so its more realistic, while shift is more of a balance between arcade and sim. i think that forza would have deeper customization.
Shifts legit, love it

Haven't played Forza M3 but it looks lame honestly, every tells me that FM3 has more stuff to it but NFS Shift is much more fun.Forza Motorsport 3 vs Need For Speed Shift?
