I use the Shield Pro, and it works great for streaming Steam games. I’ve never used moonlight/sunshine, but Steam Link has worked flawlessly for me, as well as xbox controllers, PS4 controllers, and Switch controllers and their knockoffs. My only gripe is it only has the HDMI port for 4k/60hz (HDMI 2.1? Can’t remember the number) and can’t stream the 4k/120hz my TV can handle.
