Yes, because you've been whining about AC's FFB over there for close to a year now, about the exact same issues, and when you catch flak for endlessly going on about it you come here to complain. I know you want to like all the sims and that's a great sentiment, but some sims just won't fit you, and you'll have to come to terms with that. If you don't like AC's FFB or you can't get it dialled in or it just doesn't work correctly for you, that's not a problem in itself, but it won't change much no matter your amount of complaining about it. There are only so many sliders that can be adjusted and honestly, if I tried to dial in the FFB of any sim for as long as you have with AC and it doesn't work out for me, I'd move on and let it be.
Physics or FFB? It's a difference if something is not there in the physics, of if it's not communicated through the FFB to the wheel.
AC's FFB is different from other sims. IMO there is a lot of emphasis on self aligning force and weight shifting, which is great for letting you know what the back end of the car does, but those forces can drown out detail about what the front end of the cars is going through. The understeery default setups don't help that matter much. To my mind AC's FFB works best in cars with soft suspension and anything that's tail happy.
rF2's FFB is something I struggled a lot with in the past, but with my new wheel it works very well actually. I could somewhat solve the issue I had with the rumble strips without sacrificing too much detail by setting higher filter values. IMO rF2's FFB communicates what the front end is doing a lot better, but sacrificing a bit of rear end feel on certain cars, the Formula Renault 3.5 would be an example I struggle with a lot in that regard. It takes some time to get used to, especially coming from AC it's quite the difference for me, but nothing that can't be overcome
