Yes. In my opinion the biggest win comes from goroutines and Go's runtime, which essentially allow you to write asynchronous non-blocking multi-threaded(!)code that looks like synchronous code and is as easy to read and reason about. This leads to a huge reduction in complexity compared to the callback spaghetti you often get in other async frameworks. Basically putting concurrency first in the language and not relying on libraries seems to really pay off.
