For physical, I know George Washington and CUNY were handing out lush packages (>$25K, including tuition, health insurance, etc.)
I'm going to UT to work with a badass in paleoecology, and they're giving me $13k (plus tuition, health, and a $5k research award) for 5 years as a TAship.
UT Austin and ASU were throwing money at me. But the fact that all a in physical are funded (and therefore competition between students isn't unhealthily crazy), along with the guarantee of that same funding for 5 years (as opposed to the gamble of having to pay out of state tuition in subsequent years if I couldn't land a TAship) ultimately helped me decide.
