The city where I lived was built on a cliff so the whole of it is full of hills, it's also pretty hot and humid being close to the sea.
Biking there is a sweaty, hot mess. It's not impossible but it's different from doing that on a chill european city built on a plains.
What I want to say with that? Google Stadia really seen to be something made for people who live right beside some Google Fiber pipeline. Anything less you are asking for a less-than-optimal experience.
But if you live near fiber and doesn't mind the occasional hiccup the service works, but that's all. It works. The other console also works and don't have any of the downfalls so the only reason I see to go for Stadia is price and it's a case of you get what you pay here.
