No, there's no point in distro hopping. If you install a well-supported base distribution like Fedora or Debian, they have metapackages for installing different desktop environments, and you can install those to try them out. I just installed Pop!OS's COSMIC environment on Fedora to give it a test drive, for example. Mint probably has them, too. You don't have to distro-hop to change desktop environments.
The only exceptions are:
- You want to try out an immutable distro like Fedora SilverBlue or Bazzite
- You want to try out a declaratively-configured distro like NixOS or Guix
An immutable distro might be a good choice for a newbie, but NixOS or Guix probably wouldn't.

This one?
