As an avid Go user, I think async/await is probably a nicer construct for most usecases. But Go channels work fine as long as you keep to the basics and documented patterns.

I can recommend making a utility function which accepts a set of anonymous functions and a concurrency factor. I've since extended this function with a version which accepts a rate limiter, jitter factor, and retry count. This handles most cases where I need concurrency (batches) in a simple and safe way.
