Looks are personal, and almost everyone who has the Honda bags is quite happy with them, but I like the looks of the V35 better. Also, the shape seemed to me to be more usable as it uses the area behind the mounting hoop better. The Honda bags were not actually designed for the NC700. They were designed for another bike that had high exhaust pipes - thus the unused space on top inside the brackets. I saw a picture of the "other bike" but I don't remember what it was. IT was clear, however, why they are shaped the way they are.
I agree with beemer on the bags. I was dead set on the OEM bags, but after seeing them on an NCX I decided I would get the V35's. More room is always better for me and they look like they were made for the NCX.
