Recently have found asdf most flexible, mainly because of plug in systems. https://asdf-vm.com/

New shell instances load much faster when running asdf instead of rbenv/nvm/etc… instead of having multiple processes checking multiple dotfiles for a given environment there is just a process and single file.

Just another +1 to the asdf positivity. I've now used it for years with both Windows (WSL) and on modern OSX.

The key thing is that asdf will keep your ruby + all other languages (node, python, etc.) in sync'd versions.

This. Since I’ve migrated to asdf a lot of related tasks have been easier.
