I recently found mise and have become a fan as well. I have used asdf for about a decade and it supports the same .tool-versions files so initially I used it for those exact same things.
But I use four different computers for development regularly and sometimes use Codespaces as well. While syncing dotfiles handles most of my setup, it doesn't handle binary dependencies of my dotfiles - my neovim setup wants fd & rg etc. So now those go in the mise global config. I also have a global node & python along with uv@latest which pretty much covers every tool I might want to install.
I have never cared for the fact that homebrew tries to maintain shared dependencies and several upgrades have broken stuff for me.
