I have no experience of neither bikes, but judging from reputation, I would say that the Ninja is the way to go.
Hyosung is a Chinese brand with not so good reputation while Yamaha is a well renowned brand with much experience and a reputation to live up to.

From what I’ve heard, the finish and quality of the Hyosung bikes isn’t of the sort that’ll put a smile on your face looking at it, unless fixing broken screw-threads and such is one of your major hobbies.
