I really like WSL. Some weeks ago I switched to Ubuntu again because developing is still a nightmare on Windows. But what really impressed me was how much faster it is.
What was faster? Native Ubuntu that's my experience. I couldn't tolerate speed issues on WSL
If your issues were disk speed related, you should know that accessing files in NTFS using WSL2 is very slow. You'll have to move your files to the Linux FS first.
