There is no reason to use LFE. It doesn't add anything that Erlang does not have (besides macros) and it is very poor on the documentation side.

Even if you don't like Elixir, it brings more to the table than just syntax and macros, such as tooling, Unicode support, protocols, better error messages, better debugging, tasks, etc.

If Elixir is not your cup of tea, definitely Erlang all the way.
