Double Uppercut: not so interesting?

There's the practicality of two guaranteed hits as opposed to FF kbing too far or not having enough range. Or does it not guarantee the two hits like Double Stab does?

Both hits are guaranteed.

I usually use it as a finisher or just BSpin, turn around Uppercut, turn around BSpin, turn around Uppercut, etc. The last one is when I don't feel like getting hit.
