Delusional only truth holder??? It's just my opinion. But I don't like the user interface in AMS and AC think physics just bit the same got 500+ hours in AC and arround 30 hours in AMS that game didn't catch me at all.
Anyway I enjoy the online world LFS offers much more .... spectating and chatting much eassier and more fun.
Think LFS has still best physics (offcourse some cars can be better) and I never tried iracing cause i can't buy that game and i refuse to rent a game.
I think when u learned LFS u do fine in all race sims (me average in LFS easy got some wr's in assetto) didn't like r-factor2 and automobilsta and project cars now i'm waiting for release project cars 2
For me it's simple in lfs i wave trying them not to catch my draft. But when they catch my draft i try to take inside next corner giving them as hard time as possible But i often suck at it to or the faster guys just to fast
