Gran Turismo Sport or ProjectCars2?

I'm thinking of buying ProjectCars2

I currently own GranTurismo Sport

* (I built a BMW sports seat with a Thrustmaster PS4 steering wheel with a frame so that you can adjust the seat and sit at about the same height as in a normal car, so a realistic driving experience) *

And almost all of my ProjectCars2 should be better than GranTurismo Sport,

What do you think?

Is it worth investing in Project Cars 2?

Forza is the best.

PC2 is nh better simulator, I think, but would rather play GT itself

But if then motorsport

No if then Horizon

Horizon is an open world arcade racer. You can't compare that. In addition, Horizon quickly becomes boring.
