@ucbalumnus yes you are right in saying that. But my primary point was that the 4-year curriculum at both the universities is going to be exactly the same and the intellect/experience of professors teaching these courses is going to be basically the same too (similar credentials). Hence, this should not be factored into making this decision.
Additionally, when I said “taught by Assistant Professors and Grad Students” I was referring to the combination of lecturers (professors) and TAs (grad/undergrad students) since currents students at either university have told me that during office hours I will be primarily interacting with TAs (which is also when most of the questions are answered).
