I'm more tempted by vanilla Erlang, but that's just me. Elixir looks interesting but I already got my feet wet with Erlang a while back and I'd prefer to just resume where I left off, even if it's more laborious. I usually just get my hands dirty writing a tiny app and if I find that the code flows naturally after some guided development, I tend to stick with it. C#, if a language and I don't get along quickly, I usually abandon it. The exception is PHP, which I am forced to work with despite the fact that I harbour only disdain for it and its continued proponents in the world of web development.
