This is not accurate. I used WSL professionally for 2 years until recently switching back to Linux for unrelated reasons¹. The only issue I have had with WSL is filesystem performance. However, that is largely a result of the real-time virus protection in Windows Defender. Real-time protection is practically useless and slows down the rest of your computer as well, so disabling it is a pretty easy fix.

WSL is actually a fantastic piece of software. I can't believe how easy it is to install literal Arch Linux onto my Windows machine. It's also fairly simple these days to integrate VS Code with it.

¹ I've gradually lost enough vision in both eyes that I frequently lose track of the mouse cursor, so I switched to Linux for i3wm and better keyboard controls. Otherwise I would likely still be using Windows + WSL.
