Hyper is usable, and it has become rather fast when they switched the backend a few months ago. It's real promise is in scriptability, and, unfortunately, there aren't any must-have extensions for it. I think there are quite a few low-hanging fruits for the terminal, such as better integration with documentation or using an actually good language such as ruby directly on the command line. If I ever get around to try some of those ideas, I'd use Hyper as the platform.
