I think the Samsung NP300E5V-S02IN is a better choice because of the 8750m vs 7670m, 4GB Ram (So you have one slot free for increasing RAM in the future), 750GB SATA II HDD, i3 3120m vs 3110m in the HP...

Don't know about Samsung ASS, but the thing about ASS is that it's very subjective and differs from person to person; time and space...
P.S.: After owning the HP Pavilion G6 2005 AX, I will have to warn you that it heats up like crazy, with temperatures touching 95 degree celsius while gaming!!! It's that damn hot!!!

Don't know about sammy's heat management though...
