I spent a lot of time objectively evaluating languages for a new project I built several years ago. Elixir won out. It has now been 12 years and I still believe Elixir was the right choice for the following reasons (this list is not exhaustive):

BEAM handles concurrency better than the JVM.

Elixir threads are implemented using private memory where Clojure uses public memory.

Mix is superior to Clojure’s tooling.

Elixir is easier to learn and write.

OTP is fantastic.

Phoenix is an excellent web framework.
