PS has Gran Turismo. And we could probably discuss endlessly about which one is better.

Forza Horizon 5 is the highest rated racing game of all time on Opencritic. Sony has no open world racing game at all so it loses by default in this space.

And how does that address the original poster's comment?

I think GT7 would beat it out in pure racing, it also supports VR which increases the fun 10x.

GT7 competes with Forza Motorsport, not Horizon. Motorsport is due for a new release this year, let’s see how that compares.

Sony has no answer to Forza Horizon—open world arcade racer.

They don't really need it. There's 3rd party options like Need for Speed.

There's lots of first party titles MS has no one to one answer for either. They don't have a big mascot 3rd person shooter platform game like Ratchet and Clank Rift Apart.

Forza (any Forza game) is either blatantly arcade (Horizon) or toxic online experience (Motorsport). Gran Turismo although has its own issues is miles ahead over anything Xbox has to offer. Horizon is as racing games as GTA Online for that matter
