I find Pony really interesting. It’s a strange observation given how different they are but it reminds me a bit of Java. When I first saw Java I thought “Finally, a language that takes away the madness of manual memory management.” Pony does the same thing for threads, and Actors feels like a really elegant way to solve that. Obviously Erlang has Actors to but I never got on with its syntax, and Akka but Akka always feels like it needs Scala.
