It is mostly a matter of taste, but Elixir has pipes, decent string primitives, a bit less boilerplate, probably some edges nicer in tooling or standard library, i would say thats about it, both run on the BEAM VM and compile to similar BEAM bytecode.

The killer feature is approachability of syntax. Every single developer i talked to complained about erlang syntax unless they did prolog before or already were an erlang developer. I prefer it but me and OP seem to be the few people who do these days.
