No, there's no opinon in here when you involve the "this shows that PS3 is superior to......". HEavenly Sword does some amazing things, and has a grand scale, Uncarted is different, a bit smaller. It has much highr res textures (highest we've seen in a console game so far), more polygons on characters (like way more), wrinkle mapping, procedural animation system, dynamic shadows on absolutely everything.
That's the technical side of things, that's where Uncharted smokes everything else, HS isn't really comparable, because of it's scale.
Just because you picked one PS3 game that you decided to hype so you don't seem biased won't make you look objective.
