It makes concurrent programming much simpler than using threads. Very few locking and care is needed with asyncio, as opposed to using threads. Race conditions are basically not a thing if you write reasonably idiomatic code. It might be (or not) faster than using threads, but that's not the main benefit in my view - this easiness of use is.
