WSL2 is quite a bit better than WSL1 imo, speaking as someone who has used both a fair bit. Especially now that GPU, GUI, and audio support are available on Insiders. Some tasks still don't work very well, like connecting to external devices or anything that needs systemd (like installing snaps), but by and large I've found it harder and harder to justify dual booting Linux with WSL2 available.
I thought dual booting would be a pain but what actually happened is that migrating was mostly pain free these days and I haven’t booted the Windows install for any reason.
