Quick, list reasons I should use this over Mirah.

Because there's like 3 dudes (maybe a half a dude if you think full-time) that are working on Mirah.

Mirah is cool, but from what I've seen Charlie still has to work on JRuby fulltime and there's no IDE support.

Jetbrains has pull, and I believe Kotlin will be the language that knocks Java down finally.
