You are more backward. Enemies are 10% smaller, the bigger scope, the more you feel it. They did it propably to enable triple monitor support. Guns are awful big now.
I think most of the guns got moved back to where they were before PU2 with the hotfix. Too bad. I liked the new look.
Not higher, it is like you hold the gun's stock next to your chin all the time now, instead of a relaxed position. Translation: camera moved backwards / guns moved forwards. Also, hand clipping through the laser pointer.
