You shouldn't expect to compare the two, at least as of right now, a day after BETA. I'll admit I support both rFactor and iRacing.
I'm a big fan of Rfactor 1 whaught it was very dynamic unlike other racers. Rfactor 2 Beta blows it away. I would of liked TrackIR support in the beta I know they will add it sometime.
The way the cars move seems really nice the sideways grip is good and you can balance the cars around corners , Its in the same league as i racing and Net car pro.
agree, it´s fun to drive, the feeling of grip, the dynamic force feedback in all aspects a big difference to rF1. Still a lot of work, but looks very promising.
