Nicer syntax (Subjective).

Suuuuper fast! (Not that it matters but likely faster than Go[0]).

Single binary builds/deployments (Just like Go).

Isn't crystal single threaded only? How do you make that runs fast when you're bound on a single thread or the underlying OS doesn't have async operations. And in the benchmark you linked Go is as fast as crystal and it was go 1.5 which is quiet old.

It’s single threaded (for now), but all IO is async under the hood and will implicitly yield and allow a different fiber/green thread to run.

I might be one of the few people who would prefer Crystal remain single threaded and that effort go elsewhere in the language.
