real racers - which driving sim for you?

[MarkG]

If you race for real or do track days, which driving sim gets your vote and offers a more realistic driving experience? No disrespect to "normal" road drivers, but I suspect racers will have a more informed answer.

I enjoy GTR2 and GT Legends, the latter maybe giving a more realistic feel it seems, as the cars seem more "connected" with the track than with GTR2, but I don't race historic cars so the cars are not really that relevant, although I'm sure the "seat-time" with them is helpful whatever one drives(?).

Also, are the online sims any good? ones like iracing, rfactor, LFS & NetKar Pro?? My main focus is for realistic feel of the cars, and mainly doing practice driving, but having said that, the iracing online racing structure might be fun. Is it?

Key thing for me though, is what product offers the most realistic drive??

thanks guys
