Placement is much better at Arizona, but a few things made the difference for me: The grad students there have a very heavy workload. They teach 3 sections for all years except for one fellowship semester, up to 75 students (grading for them as well). All that while they're supposed to be doing their own work. That seems like way too much for me, I value my time. Second, the main person I want to work with is considering an offer elsewhere, and as late as yesterday told me he wasn't sure if he was staying or leaving. That leaves only one person in my area of interest, and that's putting a lot of eggs in one basket. Third, they've been jerking me around a lot, (initially guaranteeing one fellowship semester, then saying that will only be the case if I accepted asap) and that seems disrespectful and like a potential red flag. I also am not a fan of the desert climate. Hope that helps to clarify!
