Even if var121 doesn't show interest, I think it's always good to show and compare multiple implementations of the same problem using different approaches and/or libraries.

Using an asynchronous library is usually "cheating" in the sense that you don't get the nasty concurrency problems that threads produce, but I consider that the advantage of using an asynchronous approach. The downside usually is that you need to taylor all your code towards the asynchronous operation instead of basically writing synchronous code that then is run in a separate thread.
