It works well - for a Windows subsystem. It is well-integrated but also separate which can be annoying sometimes.
For example, you might code in Python in VSC against a WSL folder but make a script to eventually run in Windows. You need to install and update Python twice then - a Linux and a Windows version (obvious, but can be annoying).
WSL is also really slow, especially for filesystem heavy stuff. You know how on Linux programs sometimes run faster via Wine/Proton than on Windows itself? Yeah, this is the other way around.
