How Do These Theoretical Physics Programs Rank in High Energy/String Theory?

[spaghetti3451]

Would you be able to provide an assessment of the high energy/string theory theoretical physics ranking of the four programs below:

Graduate program in University of Florida
Graduate program in University of Alberta
Graduate program in UC Davis
ICTP Postgraduate Diploma (High Energy, Cosmology, Astroparticle Physics)

I'm looking primarily for the reputation and availability of high energy.theory/string theory professors as advisors and the chances of a good postdoc job offer after graduation.
