I'll do my best to help since I applied to both schools and was invited to interview at both:
1. Consulting - Both schools are equal here.
2. Tech - I'm not sure, honestly, but I expect both are equally strong as well.
3. Entrepreneurship - I've heard fantastic things about entrepreneurship resources at Booth, but I haven't heard the same about CBS. Check out http://www.mbaover30.com
if you're interested in the impressions of a student who got into Booth and is interested in entrepreneurship.
4. Other options - Both schools will open many doors for you. Personally, I didn't like how flexible the Booth curriculum was. In fact, you can look at it both ways: the flexible curriculum allows you to try different things, but, on the other hand, if you're unsure what you want, you could end up wanting to take a little of everything and ending up with no deep skillset.
5. Ranking - While Booth has been on a great run recently, I don't see it as an objectively better or well-renowned school than CBS - they are both in the fabled "M7" after all. Since you mentioned you're an international student, I'd also suggest you think about which school is more well-respected in your country (assuming you want to go back).
6. Cost - I have lived in neither NYC nor Chicago, so take this with a grain of salt, but Chicago would be much cheaper. Businessweek has the costs pegged at $120K (CBS) and $110K (Booth). For what it's worth, the Booth student budget for housing is $14K and the CBS budget is $21K.
7. Culture - I didn't get a chance to do full visits at either school, so I'll pass on this one.
8. Social life - Again, I haven't lived in Chicago or NYC, but I wouldn't want to live in NYC (that's just me). I'd say NYC has more going on, but Chicago is the 3rd most populous city in the country, so it's no slouch either.
9. Campus - The Booth campus is much nicer than the CBS campus, but that shouldn't be a determining factor for you.
10. Year internship - I don't know about this, but again, Chicago is a huge city, too. Many opportunities will also be available at Booth (that is, unless you want a niche finance job that only exists in NYC).
11. Weather - I believe the weather is milder in NYC, but probably not by much. For perspective, I live in the Boston area (it's generally colder here than NYC) and I've had several Chicago-born friends tell me Chicago weather is pretty similar to Boston weather, albeit slightly windier.
Sorry I couldn't answer all your questions. I hope that helps!
