Firstly congratulations on your unconditional!
No one can make your decisions for you but in the first instance your options are really constrained by your financial situation, we're talking the art of the possible depending on the support available.
You also don't say what you're studying - how often and for how long you're going to need to be in university each week. If you're only in lecture and seminars a couple of days a week then commuting starts to make more sense.
Although a big part of university is learning to live away from home and do your own admin', commuting can be done successfully, I know one lad commuted a couple of times a week to London from Lincoln and saved himself a
fortune compared to living down there
.That being said, as you mention, commuting means you can miss out on the social/sporting/society side of things which often involves the evenings. but university is not one long party, neither your liver nor your results would stand it: and you get your washing done and dinner on the table at home - it's a balanced decision.
Rest assured, you will make friends on your course, and for the big night out [even the accidental ones] you can always bag a bit of floor - stashing a sleeping bag and a change of clothes might not be a bad idea
.
More important, how will commuting impact on your access to necessary resources? Can you do everything you're going to need to do from home? For example will you be required to do collaborative work or will your "homework" just be reading at home?
It's worth remembering that nothing is forever, if you commute the first year and feel it's not working out for you then you can look to jump onto a flat share in the second - and vice versa. Best of luck
