It's pretty nice for server code, but still has one major shortcoming which is that's it's kind of tricky to write high-performance IO-heavy code (it's easy if you want to have a thread blocked on every IO request, but that's bad for performance if you have many concurrent requests). This will improve a lot once async/await stabilizes. It already works great in nightly if all of the libraries you want to use support it.
