Your mileage may very depending on a variety of factors. I got a free Stadia kit (controller + Chromecast Ultra) for being a YouTube Premium/Music subscriber, and decided I'd give a good and honest attempt at playing through a full game on Stadia.
I played through Superhot and the best I can say is latency is impressive given it's beaming my inputs to a server, rendering, and beaming the frames back to me (though still not as good as just playing locally). But I had some horrible issues. Several play sessions had to end because my internet was being unreliable, as home internet tends to do. Not sure if someone started streaming Netflix or what, but that's kind of the issue -- I don't want someone else doing something on my network to be able to affect my gameplay session. Or if my ISP is just experiencing high traffic, or if the internet in my neighbourhood goes out, etc. There's so much that can and does go wrong, even if it's 99.9% reliable, that's not near enough for a video game.
Thankfully the game I was playing wasn't particularly time-sensitive, if it started lagging I could stop for a second and the game doesn't move forward (that's just how Superhot works, for anyone who isn't familiar). But I was seeing on the front page of the store you can buy Celeste and I just could not imagine playing a precision platformer like that with the bit of latency that exists, plus the possibility I get a lag spike and by the time it catches up I'm already dead and restarting the segment.
