I just got into Northwestern yesterday after being on Hold for about a century, and now I'm looking for some advice from the people who can give it best: complete strangers

I have already put down my first deposit at Georgetown, visited the campus, and enrolled in the housing lottery, but it seems that now I have something new to consider, and I would love to hear some honest opinions on which is the best pick: Georgetown or Northwestern.
Factors:
1. City - I've visited both, and I can confidently say that I liked D.C. better than Chicago, but I didn't dislike Chicago at all. Though as a Californian born and raised, the winter there might be a pretty intense change.
2. Class size - NW is much smaller, GULC is enormous. Does is matter? Will that really affect my job prospects if I graduate with the same relative ranking from one or the other?
3. Job Placement - I have been reading things about not-so-great job prospects after GULC. Is that simply a product of there being so many students, or is there something seriously wrong there. And secondly, I would much rather work on the East Coast than in the Midwest, but is one truly better at placing people there than the other?
4. Other - boyfriend will be in grad school at MIT in Boston. DC is closer. Just throwing that out there so as not to pretend that's not a factor

Any other insight people have on either school would be HUGELY appreciated, and I look forward to the kind and the snarky with equal anticipation haha.
