I have no idea since I haven't driven them IRL. To me, all those cars handle great in GTS and are very fun and rewarding to drive fast. However, they all have severe lift-off oversteer, so, you either need good FFB and skills, or a gamepad which has built-in assists to not let you steer too much on lift-off - otherwise they feel unpredictable and totally unfit/driven to be driven anywhere at all.
IRL, I come mostly from motorcycles. Most sporty motorcycle have very neutral handling, like a perfectly balanced race car in GTS. However, I have driven 250 hp normal cars on both twisty roads as fast as I can (professionally) and on track. I also have a Toyota Corolla 2021 as everyday car. I can't feel anything in the wheel of those cars, just a weak self centering torque. Going fast and safe is done with my "butt gyro", exactly as on a motorcycle where I can't feel anything in the handlebars. The only difference on a motorcycle is that the handlebars become stupid heavy in high speeds when you want to quickly lean the motorcycle a lot, so you have to twist and counter-steer with a lot of force - otherwise it just stays upright and kills you.
I actually have seen those videos already, and I enjoyed them a lot!
My conclusion so far is that ACC and GTS uses different "FFB languages". I'm used to the "butt gyro" language IRL and have gotten used to the "butt sensations" in my wheel in GTS. Losing those entirely, and instead having self-aligning torque, tyre-whatever-something, road texture and so on, indeed feels different and I can't drive properly with that "language".
I saw that IrFFB has come to ACC, as ACCFFB. If I come back to ACC, I'd definitely try the "seat of pants" effect and try to emulate the FFB language GTS uses.
If you struggle with G-force sensations in GTS, I'd advice you to try 1/1 in FFB settings. Or increase max torque to 5 as most. Increasing sensitivity gradually kills "butt gyro" and the wheel becomes heavy most of the time.
