The pros of USC for me are:
smarter student body
Which mean you will have stronger academic competition for those A grades you need to create a strong application portfolio to med school.
the center for mindfulness science
the brain and creativity institute
seeing a lot of premed success (plenty of premeds getting into top med schools every year)
USC attracts far more pre-meds than Temple does. USC produces 360+ med school applicants/year while Temple has around 160. At USC you will be more a number than at Temple.
Also “top” med school is pretty meaningless. In the US, medical education is flat–meaning that all US med school (MD and DO) have a standardized curriculum and all US med student take the same qualifying exams during med school (USMLE exams) that are used to help place students into residency. And I’ll let you in on a secret–where you do your residency is far, far more important than where you go to med school. Residency faculty are the ones who will help you get your first job–whether it’s in private practice or academic medicine.
Better area/opportunity to live in LA
But realize that as an OOSer your chances of enrolling in a CA med school are very low. CA is the largest single producer of med students in the US, most of whom attend OOS med schools.
I will also mention that the area around th USC campus can be pretty sketchy, esp at night, though the campus itself is safe enough. You will need to exercise your “city smarts” near USC/in LA just as you would in any large urban area.
