MrIndigo is right on the money. Honestly, when you get to the top tier, they're all about the same education wise as long as they have a comprehensive program in your major. You'll learn a lot everywhere in the top tier, not just MIT. Stuff like that is far more variable between campuses so be sure to focus on that rather than counting the number of perfect SAT scores they reject.
In addition, very few careers actually care that much about where you went specifically within the upper tiers. Older, more "elitist" professions tend to care (law firms, for instance, tend to select predominantly from older universities of classic repute; I think medicine is usually the same), but for anything else it rarely matters more than incidentally.
Also, while I have no personal experience with much of the facilities of this nature, Student Unions (or whatever the equivalent is in your nation) usually have a bunch of really important services on offer, including but not limited to:
- legal aid/representation/advice; students frequently run into legal issues in regards to tenancy rights in rental properties, industrial relations and losing their job or being exploited, sexual/racial/other discrimination.
- Job finding, employment and recruitment services
- House and housemate seeking
- travel services; arranging visas, cheap travel fair, advice and information
- advice for education issues; appealing unfair grades, career plans.
- Childcare services.
For a lot of students, these sorts of services are invaluable, and are well worth checking out when choosing your college.
EDIT:
At Imperial my course was physics with theoretical physics, everywhere else was a general physics course.
I don't think that is actually a different course. Every university in the world teaches physics as a combination of experimental and theoretical components. (Normally, your lectures/exams are geared toward theoretical stuff, but you'll have other assessments of experimental/practical nature).
