Not OP but I've used Crystal in production at 3 companies: Qualtrics, InVision, and my own side-company (~40 employees) which I briefly mention in this podcast[0] from a few months ago.
We do, but only for a few smaller services. It's great, but most of the things we do aren't CPU bound, so we use Ruby. Personally, it's become my default for side projects.
