Apply to both, but if you get into Arizona- choose them over ASU
they've been around for a while, #17 on the T4 list. PR ranks them #6 as 'most competitive students' -- not sure i care much for that.
they did send me a nice personal email, as opposed to the 'dear computer science/engineering major' one i received from wm & mary.
anyway, if you know something about them, or even have an opinion, i'd appreciate it
