You should try it again. I had a similar experience to you about 5 years ago and completely gave up on game streaming.

However, I had a cold a month or so ago and wanted to play Oxygen Not Included from the couch from my old-ass Linux laptop which couldn't run it. I set up Sunshine and Moonlight in about... 5 minutes? And it "just worked". And worked well. I was able to play perfectly, and that is including my host machine being on WiFi even though all the documentation says use Ethernet if at all possible (which ofc would be better).

It was honestly the most magical thing I've done with technology in the past few years.

Disclaimer: this was only for local/wifi streaming.
