Hey Shllemon, I think that they are both very strong in labor. If you find macro interesting, then you may also be more interested in structural work than reduced form work. Check out Moshe Buchinsky at UCLA and John Kennan at Wisconsin--they are both applied econometricians who do structural papers in labor. Wisconsin is ranked higher and is reputedly better at econometrics. If you're having trouble deciding make sure you exhaustively look through each department's website and faculty profiles. Good luck!
