The major benefits over a fully managed VM from my exp. with it have been

- easy integration with the Windows filesystem (it's automounted into the WSL env)

- Using VS Code to work with files in the WSL2 env. works out of the box (just type `code .` in a WSL windows)

- It's very quick to spin up new WSL2 instances. you can just use `--import` and it'll bring in a tarball to create your new instance. You can even export a Docker image and use that as a WSL instance base filesystem which is handy.

- Docker for Windows works pretty well for most usecases and you get one shared Docker instance across all your WSL setups.

Sure I could do all that with discrete managed VMs but this is easier
