Applied Math Maryland vs Arizona

[BG7]

So I got into the applied math programs at Arizona and Maryland (but not Cornell ). At the moment, I will probably pick Maryland because it has a better overall reputation than Arizona which matters to me since I don't have a clearly defined research interest. I could go into physics, astronomy, fluid dynamics, numerical analysis, or dynamical systems/DEs. Luckily both programs are very interdisciplinary, so thats why I thought they were great matches for me. Does anyone have any detailed thoughts or opinions about these programs? For now, my main interests are probably in astrophysics and optics
