Nobody stays in Linux for the GUIs? Heck if it purely a GUI decision I'd move away from the horror of Linux, the fact that the best "GUI" being told are TUI tells you more than enough of what people's priorities on Linux are.
I would switch over to WSL in a heartbeat if speeds were 60-80% of bare Linux (cpu/memory) and every other subsystem was interoperable / accessible with Windows (cough network) which was my main issue with WSL, anything that wanted to run services was a disaster in WSL (DB/exposing port to host/etc).
