The Verge had this say between the two:
-------------------------
"Where Samsung falls behind its direct competitor is in the actual feel of the phone. Although the sides of the white Galaxy S III and the front of the dark blue version both sport a brushed metal look, they're made out of good old plastic. Alas, as much as we wished Samsung would move away from cheap-feeling (if sturdy) materials, the GS III is just keeping up with tradition. The glossy back is now more in keeping with the original Galaxy S than the textured finish on the Galaxy S II.
The main takeaway when you first pick up the Galaxy S III is that it's surprisingly light. It weighs over 130 grams, so it isn't that much of a featherweight, but the sensation of holding it is one of weightlessness. It almost feels hollow. We're not huge fans of this, we appreciate a bit more of a reassuring heft.
We had to look really closely to be certain, but sure enough, this is another Pentile AMOLED display from Samsung. The big rumor going into this event was that the Galaxy S III would be the first HD Super AMOLED display without Pentile spoiling things, but check out our macro shot below for some definitive confirmation (the signal strength indicator is supposed to be white)."
