You’ll have to judge Linux remote desktop clients across many aspects to find the right one for yourself. For starters, you’ll want to pick something that offers high performance and can run on your hardware. If your hardware’s too old, a lightweight client will be a smarter choice.
If you’re a power user, you’ll want a neat interface, customizability, and added functionality, like hotkeys. You’ll also want to check whether the client supports multiple sessions and what kind of security and privacy measures it takes.
