I understand there are two sides/groups here: 1) Those who think errors are important to control flow, and 2) Those who think errors are exceptions to control flow. If you are in group 2 both Promises and async/await will give you neat and simple code. But if you are in group 1 Promises and async/await will be really complicated and ugly because each await will be inside a try/catch. Because I'm in group 1, I try to avoid Promises (and thus async/await) in JS because the promise will capture all future errors, and if you forget to add a .catch, that error will never surface. Promises make asynchronous code more complicated. Async/await however get rid of a lot of the complicated syntax, so when I do not care about errors (eg. errors are exceptions) I use async/await because of easier control flow.
