Pop! Is Debian based I believe, so anything related to Ubuntu/Debian/Mint will be basically the same. Once you start getting into Fedora, Nix, and Arch is where you get different experiences with package managers.

You can also mess with shell stuff by installing different shells (nu, xonsh, fish, and zsh are the big ones) those don't require a distro change either, they're available as packages and you can change your user shell with the chsh command, or just run them and do what you want before dipping out to bash/dash
