I’d pick Berkeley, specially if you got Regents.
It’s more fun to go to a school as well-rounded and diverse as Berkeley. Berkeley has everything MIT has. MIT is still predominantly a STEM school full of (sorry to say this) unattractive geeks and nerds.
Also, the general conception these days is Berkeley engineering is as prestigious and respected as MIT. It’s now just as exclusive, too, both having below 8% admit rate. And, Berkeley has close connections to SV. If you’re eyeing to become a startup founder, go no further. Berkeley is now ranked number one in terms of having the most number of successful startups and startup founders. Stanford fell to number two, and Harvard is again ranked number three.
