If ok I also want to share my thoughts. Keep in mind that I played AC a couple of hundred hours in 2017 and GTS only 3 hours. ANd GTS I only raced with three cars in default setup!
First time I started a hot lap in GTS was Brands Hatch with a VW Scirocco The track is very clean and also the known markers for braking etc are missing (maybe because it is an unfinished Beta?). After 5-10 minutes I really thought what is going on. I completely missed the 'feel of the wheel, car, track'. With AC you have much more the idea that you handle the car and it responds way better on steering, braking changes. Also FBB/T300 is very weak in the beginning.
Then I turned up the FBB, sensitivity, responsiveness. This already improved a lot. But still braking is like floating on ice. For now GTS is more Driveclub then AC or PCars (with regards to physics)
Next time trial was a Subaru WRX on that new Dragon Trail track. Very refreshing new track.
Hey it seems like the car is doing more what I want it to do in comparison with the VW Scirocco. Better connection between your input devices and how the car behaves on track.
Overall AC seems to be a league on its own with regards to physics on console. That we already knew and is still the case. GTS feels like your floating/hoovering over a very wet track (only for now?). I personally miss the realistic physics behavior of the cars on track.
But to end a little more positive for GTS : it is a graphical superb race game (not a sim...) and it has a huge potential. I already pre-ordered the CE edition and I have no reason to cancel that
.
Again may be this is because of a beta with a complete other testing purpose then testing physics? Time will tell.
Also curious to other racers and their thoughts about AC vs GTS physics, car handling etc.
