rustdesk just works, moonlight and sunshine is janky as hell outside the local network due to the fact it uses like 5 different streams.
I have never once gotten rustdesk to work. I don't try anymore.
I had a heck of a time ever getting that to work. Also, can that support multiple concurrent users?
From personal experience, Moonlight is pretty slow and high latency. Even Microsoft's RDP is better.
I don't understand how this can be, you can play competitive games over moonlight/sunshine, and I really don't recall being able to come close to that latency on RDP (though I haven't tried in about a decade)
I had a weird setup: a rented airgpu.com machine, and I connected from my M1 MacBook Pro.
