Physics : Boston University vs UC-Davis

Hi everyone!
I’m an international student and I got into those two great Unis few days ago for next fall.
I will major in Physics, and I’m 100% sure that I’ll will continue my graduate studies in Theoretical Physics.
I would like some advices on those two colleges, which one do you think is better, if you’d to choose?
Since I’m international I don’t have the opportunity to visit. For now, please, limit your discussion on this parameters :

  1. Prestige of the University
  2. Physics Program
  3. Research Opportunities for Undergraduates (in Physics)
  4. Internships for Undergradutes

I know, there are other factors to take into account (as campus, city-college vs town-college, east vs west, cal vs mass, sun vs snow, costs ecc) but, please, do not take into account for now any of these.
Thank you so much fot any help you’d give me!

bump?
