For me, Sync only worked well to make phone calls ("Call Joe")

And during a brief period, I also had a windows phone, where you could say "Call Cortana". Cortana was registered as a fake contact behind the scenes, and all it would do is trigger the Cortana assistant through that phone call. You'd then tell Cortana what you wanted, and it had much better voice recognition and capabilities than Sync, so it did what you wanted 99% of the time. It was pretty cool.

Of course it was annoying and a waste of time as you had to always make that call first, but I'm glad the engineers on Cortana remembered that "all problems in computer science can be solved by another level of indirection"!
