Clinical or research focus for me. I want to be in private practice at some point so I didn't even bother applying to some of the research based schools (Columbia, etc).
After that it comes down to the general atmosphere I felt and whether I felt like they were trying to 'hide' something from me on the tour. Believe it or not, of the three schools I've interviewed seemed 'sketchy' and didn't feel right... Like they were trying to hide something from me that I wouldn't find out about until after starting.
After those two, if two schools are clinically focused and have a comfortable atmosphere then it just comes down to cost for me: in-state or out-of-state.
Hope this helps
