I don't know about anyone else, but if any of these cloud gaming services want me as a customer they need to give me access to my existing Steam/GOG/Epic/Whatever library on their cloud system. I'd also much rather build my own system though, unless they put a datacenter in my suburb I don't see this ever being a better experience than my own machine.
