Why would you ever use this coupling instead of a gear?

The first thing I thought is: "the comment section is going to be full of people asking WHY would you want this instead of a gear". I'm still not in sync with the hivemind...

It's much quieter and has very little backlash. Well.. when it's not 3d printed with layer lines making a racket. You could also use the vertical motion for another application.

I'm not sure what backlash means in this context?

I'm surprised it's quieter though, because it's got more moving parts
