I have used it on my Series X and it's just not as good as playing it locally. I've got it hooked up to a 4K120Hz TV that supports VRR and ALLM, and the exeprience over the cloud will never be as good. It's very convenient that I don't have to download 50GB to play a game, but if it's a game I want to actually play, the 50GB is worth it.
I also have a PS5 with the PS+ Premium package, and their cloud offering is even worse.
