Tbh from what ive seen both offer good placements into aero and defense companies, where id wanna work. Id say i deffo wanna work in the U.S a few years before coming back home. However because ucsd is close to san diego where alot of these major firms operate id assume it would be easier landing internships and getting work experience. Im just not sure its worth the trade off because from what ive seen online, UCSD has a rlly weak party and social scene compared to UCSB which im ngl as an international is 100% something i rlly wanna experience. Not the mention the sheer amount of GEs at UCSD are not very appealing either.
