Mise is pretty nice, I'd recommend it over all the other gazillion version-manager things out there, but it's not without its own weak spots: I tried mise for a php project, neither of the backends available for php had a binary for macos, and both of them failed to build it. I now use a flake.nix, along with direnv and `use flake`. The nix language definitely makes for some baffling boilerplate around the dependencies list, but devs unfamiliar with nix can ignore it and just paste in the package name from nixpkgs search.
There's also jbadeau/mise-nix that lets you use flakes in mise, but I figured at that point I may as well just use flake.nix.
