Besides the rant in that article about syntax, this is one of the main reasons:

These shims have terrible performance, adding ~120ms to every runtime call. mise activate does not use shims and instead updates PATH so that it doesn’t have any overhead when simply calling binaries. These shims are the main reason that I wrote this. Note that in the demo GIF at the top of this README that mise isn’t actually used when calling node -v for this reason. The performance is identical to running node without using mise.

Personally I also still use asdf and I like that in all years of using it I never had to debug it, it just works!

On a Mac I’d recommend asdf, which you can install via homebrew. Than you can install OTP 27 and a compatible version of Elixir, and have different versions per Elixir project.

Or mise which is a newer implementation based on asdf.
