I've only given Crystal a cursory look in the past and I think I'd enjoy working with it but can't speak to whether I'd feel as comfortable and productive as with Ruby (maybe I would). But what I do know is that you would not have the vast amount of Ruby gems available to your project, so if you feel the need for those as I often do then you might find it a bit more slow-going.
