Agree with most of you, except for these.
Forza 7 is not GT at all. NONE of it gives me the GT vibe, whereas GTS gives me a ton of those.
No way is this game a $40 title. Especially if you can live with Forza 7, which is mostly recycled really, being $60 with microtransactions written all over your face. When I play FM7, the feel of cheapness of the developers constantly rub on my face.
The campaign mode in GTS is not the same thing as in FM7, although I don't think FM's campaign need a lot of care either because it is basically random races put together with cards. Hell, it can be generated by a computer. And when it comes to that, it doesn't matter if the races are pre-defined or "defined by you", which, is a function perfectly usable in GTS. If there is one game for which a "campaign mode" takes time to make, it is Need For Speed.
Lastly, again, the amount of polishing of GTS is simply on another level compared to PCARS2. It looks MUCH better than PCARS2 on the same hardware, has way less bugs, doesn't require hours of settings to work well, and looks simply more realistic than PC2 even at max on PC. Surely PC2 looks good, but it is never realistic to me, it only looks good for its own right. I admit Forza 7 is gorgeous looking game as well, but it lacks a lot in the little details graphics-wise which occasionally brings you out of the immersion, such as when your car doesn't cast shadow on AI cars (this has been there since FM5, makes me wonder if there's anybody ever thought about this). GTS represents car handling very well --- on par with PCARS at least, and works much better with a wheel than Forza does. Little things that never before considered by others, such as the motion control with DS4, works amazing. It sure lacks a lot of things, but it also does a lot of things much better. I'd never tone down a game only for its cons and ignore its pros.
