Your list has 1 mixed, 2 self-catered and 2 catered colleges in your top 5 - this is all good if you don’t have a catering preference, but unusual. I think you can have a good social life in any of the colleges if you want to at Durham.
Cuths and Hilde Bede don’t tend to be ridiculously popular, so I think you have a strong chance of being allocated to one of those. I am surprised you have St John’s 3rd, even though it is a lovely college. The chances of an en-suite are low without a medical need and there are shared rooms. It is also very small, so even in 3rd you are unlikely to be allocated it.
