ASU itself is nothing to write home about (it’s very large and overcrowded, with lower-achievement students), BUT astronomy is excellent and, most of all, the Barrett Honors College is among the top 10 in the entire country. Barrett ensures you’ll have an excellent experience academically&socially speaking, and won’t have to deal with the C+ doofus who enrolls at ASU for its party reputation. You’ll even have your separate, 9-acre mini campus of hotel-level residences and restaurant-quality dining hall (may make it hard to adjust to dingy first apartment living after you graduate…).
ASU itself is less good than UAZ, but the Honors COllege at ASU is much better than the Honors College at UAZ. You could apply to both and decide once you’ve been admitted.
