Hi! So first of all, your college choice won't impact your degree itself; as you probably already know, you share lectures with people from all of the different colleges. Personally, all of my supervisions are outside of my own college as well. If your college doesn't have fellows that supervise certain papers, you will just be assigned a fellow from another college, and honestly this is a great opportunity to explore the different colleges! Choosing a particular college also won't impact your chances of getting in; the winter pool pretty much guarantees equal opportunities if you get through to the interview stage, and for History, there aren't exactly "more popular" colleges that could limit your chances pre-interview. So don't focus on those statistics too much.
There's a page on the Cambridge University website about choosing a college and it basically comes down to personal preference. I think the important criteria for most people are these:
Bigger vs smaller college. A bigger college has a larger community, and you will meet lots of different people. It will probably be easier to find people within your college that have the same interests (although societies are great for that too, and they're often uni-wide). A smaller college might feel less overwhelming if you're very introverted, and probably has a more "cosy" vibe to it.
Architecture. People might say that it's superficial and that it shouldn't be your main reason for (not) choosing a college, and although they have a point, it makes sense to pick a college you find pretty if aesthetics matter to you. Some colleges have very old buildings, some are more modern, some have many green spaces and others only have a lawn that you can't walk on lol.
Accomodation. Some colleges offer accomodation on-site, others spread their accomodation throughout the city. Rent is also more expensive at some colleges. Modern accomodation blocks are generally more comfortable to live in.
Food. Honestly not one of the most important things for many people, but if you're torn between two colleges, it could be a deciding factor. Not only the quality of the catering food, but also the kitchens. A lot of them don't have ovens or freezers, so if you really enjoy cooking or baking, you might want to pick a college that has those. Or you could join a baking society and just use their oven lol.
Distance. Colleges in the centre are convenient, but touristy/busy. If you pick a hill college, you might need to cycle. But to be fair, Cambridge isn't too big and you won't have to commute far anyway.
And, perhaps most importantly, atmosphere. The college websites and the virtual tour give you a general idea of what a college is like, but if you can, attending an open day will be incredibly helpful. You can walk around a college and ask yourself: do I really want to live here? You can talk to current students and staff, ask any questions you might have. If you get good/bad vibes from a college, just follow your gut!
But the most important thing: don't overstress it. Many people end up being pooled, and they all love their new college. I haven't met a single person here who's unhappy with their college, and there are amazing people everywhere, no matter where you apply.
I hope this was helpful and if you have any further questions about History or Cambridge in general, feel free to ask! Good luck on your application
