Yes, A sound cue provides you with an editor to perform more functions on a sound wave (such as delays, groupings, blueprint parameters etc). Many of those features are also available on the sound wave, it’s just less flexible. There’s really no difference on the users end, other than that they can do more with the sound cue, and there’s a lot of BP nodes tailored for sound cues.
But you can of course stick with the create sound method if that’s what works for you.
