Notwithstanding the new VS UC seats, I'd say it's better. The NZ leather seems more tightly pulled and yet feels softer than the somewhat flimsy leather on the VS seats. The bed forms by the top of the seat flipping forward (watch out when this happens!), which exposes the "other side" of the seat of a softer fabric covering (which you further put a light overlay on top); on VS, the seat simply slides forward (as you'd "expect") and you have a thin cover sheet. The area inside the seat seems a bit bigger, too.
But yes it's essentially the same seat (and NZ had to pay VS for the rights both for this BP seat and the new BP seat).
