Superior in ergonomics - launching several async tasks and combining their results via futures is is much easier compared in Java compared to to Go's low-level, primitive way of doing things. No need to explicitly create channels and wait on them. Go doesn't expose Go-routines as a type and hence you are brow-beaten into laboriously using channels even when there is no real need to do so. I guess this could be all sorted out if the Go stdlib offered some convenient structured concurrency packges.
