Campus uni's are great if you always want to be around other uni students. It feels very much like a bubble and everything is close by when you're living on campus (the walk to the library for me is 7 minutes long) and you're always close to a gym/field. It's also way cheaper since you'll probably be going to uni pubs/bars and likely not using public transport.
However, you do usually miss out on all the coffee shops, restaurants, shops and the choice you get that you would in a city uni.
Having spent most of term 1 and all of term 2 in lockdown, being on campus has been great because you get to see your friends that are on campus and its way less alienating.
