Stadia is riddled with latency issues. Taking numbers from Gamers Nexus review (https://www.youtube.com/watch?v=m0gILReDQsY) in a high framerate game it has 85ms input lag (22ms for local play) and low framerate games it has 110ms (61ms local). Of course these numbers depend a lot on your internet connection.

Even with mediocre routing Steam Remote Play beats these times by being 3x faster while also moving more Mbit. (~40 ms, 25 Mbit.)

The limitation on speed there was the ISPs insane peering scheme - Orange Poland is a dinosaur so everything cross network (that does not pay their scalper peering rates) got routed out of country and back.
