I haven't noticed any significant differences, but then I don't use it that much or for a lot of different things. I also run Cygwin, and I have Ubuntu running in a VM. I did try to compile ffmpeg recently, and that failed. Cross compile under Ubuntu/VM worked okay, but took a very long time. ON Edit: Followup to my original reply. I was able to upgrade Ubuntu 20.04 to 21.10 under wsl2, no problems doing so. But that didn't fix the problem with compiling ffmpeg. I use the Cygwin utilities (find, grep, du, etc) every day under Windows, and when I really need unix, I run Ubuntu under VMWare. I just don't find much use for WSL personally. It doesn't cost anything, and it doesn't hurt to have it there and available, but I just don't use it really. YMMV
