I am not sure about a "professional" experience. But my personal one is that I had my parents install it on their machine years ago, and since it's running stable and without great changes or weird banner or any other silly stuff that would break the flow.

I can log in remotely and help them. It is also easy to install and run, which is also bonus points.

For me, this smooth experience has been a godsent. When I used TeamViewer I feel like every time I would use it, sometimes months apart, it would break or something would change.

I use it to help parents when they need to create/save some document. I haven't use it in a year, don't remember the performance, or at least I didn't notice any problems with it for my use case. The problem I had was with screen scaling. I am using 4K screen with 200% scaling, and my mom is using full HD with 100% scaling. Her remote screen was tiny.

IIRC you can host your own sever instead of using default one, not sure if it would help with performance.

Works great both Windows and Linux. Only difference I noticed with Teamviewer is that it asks for windows Administrator permission to take control meanwhile Teamviewer I think it does not.

Apart from that (and if you tell your users in advance it means nothing) experience is on par.

I also installed my own server for vanity domain but went back to free cause I was not vane anymore.

I use AnyDesk daily, but sometimes have to use RustDesk when it can't reach clients in certain regions.

Performance is great, supports multiple monitors, keyboard sync and everything you'd expect for a remote tool. One lacking feature is account naming, which AnyDesk has.

I find similar performance to AnyDesk most of the time but RustDesk never seems to get sluggish, while sometimes AnyDesk gets very slow and my view of the remote machine gets up to a few minutes behind, which is pretty unusable.
