After finally watching all 3 I woul dhave to say Sony for me did the best. Although I did breeze through the 1st hour of the show because of crap I didnt care about like the PS Move or the 3D stuff. The games they showed were what was important for me, even a couple titles on the PSP.
Plus getting Gabe Newell to show up on stage was quite impressive, him even making a joke about it.
I was also impressed to see the amount of exclusive DLC Sony paid for.
