I attended the “Other Place” but my serious answer is the same for Oxford. Research online which colleges are richest (and most prestigious) and apply there unless you have a strong reason to prefer another college. The richest colleges have more grants, funding and opportunities available to students—you can save thousands of pounds and get access to opportunities just not available elsewhere. (For example I found out early on that my peers at another Cambridge college received a grant for books 3x larger each term than my college did—which in turn was more than another gave all year) - likely the additional additive networking opportunities are equally as valuable. Connections to well known EA’s within faculty are probably overrated, unless you can be sure of a close connection to a faculty member for several years (as what Cambridge would call a Director of Studies) you won’t gain a significant advantage and you can pursue the interests outside of your formal study program.
