Agreed. If I need the best performance out of a Remote Desktop, thankfully there is Sunshine⁽¹⁾ and KASM,⁽²⁾ though it requires significant setup beforehand and bugs do crop up on certain desktops + window protocols.
RDP as a regular or quick solution is actually really decent in this respect.
KasmVNC has worked great for me to setup development VMs which require GUI work. Kasm Workspaces is an interesting product which allows you to create disposable desktop sessions. I use it to test software, setup a particular configuration, then throw it away.
