WSL gives you a full Linux distro. You can use Debian, Fedora, Ubuntu, from the top of my head. These are default options. There are others available. Additionally, you can bootstrap to other distros. I know Arch was an early target.

WSL1 replaced the init process. For Ubuntu, at least, snaps were not enabled, at least out of the box. There were occasional issues early on where the syscall translation was not perfect. For me, at least, these were all ironed out after a few revisions. Unsure if there were still edges I didn't hit.

WSL2 takes advantage of virtualization technology, so should be an even better Linux experience.
