Yes, from what I have seen so far Resistance 2 and Gears 2 both meet my expectations (unlike for instance Halo 3 and Mass Effect)
Regarding technical graphics superiority I referred specifically to the huge bosses. Overall I think more time was spend on Gears 2's assets to make everything look as slick as possible from an artistic standpoint. I think Epic made a similar point in an interview, the graphics artists invested a lot of effort to make the underlying technology look as slick as possible. Obviously Insomniac as a small company doesn't have the same manpower and Resistance 2 was a huge enough undertaking as it is.
