NoMachine is a great alternative for RDP. My remote desktop only had Win Home which have the RDP features disabled, so NoMachine is an answer to that. There is a command line to enable the RDP in WinHome but it require several step and external library to make it functioning. Now I have a new Intel NUC with WinPro, so I ditched NoMachine for MS RDP. NoMachine works flawlessly on macOS and Windows (and it have Linux support). I would say NoMachine is trailing behind MS RDP while Apple VNC is closer to the totem pole.
