Mise just works and takes maybe 1-2 minutes to explain and have a tool running on a team members machine in my experience. I couldn't get into nix, too complicated for me and I've yet to find a resource that makes it click for me. After that I would feel comfortable encouraging the rest of the team to use it but as mise is so easy and even more popular, I will probably just stay using this. I will look into devbox though, thank you for the recommendation!
I hear you, Nix has been nothing but a waste of time for me every time I tried to do anything with it.
Devbox abstracts it and the only time I had to do a nix-specific thing was when I needed a flake to install a CLI from a GitHub release.
