Hey, currently a first year staying in North Village! (sorry this is gonna be long, but I wish I had this advice before uni so hope it helps!)
I love North cause its a small community within the uni and when you make other friends apart from flatmates (course/societies), its so easy to see them for a chat/to go to uni together/for help or even just going out. I personally don't find it cliquey but ig thats down to individual experiences, it's quite lively and loud as well which I like. Obvs you have to get the bus into uni everyday (not for the weak in the mornings!!) but you get used to it and the bus gives me time to just relax.
UH is a bit dated and old (I've got quite a few friends there) but its cheaper than all other accoms so the price reflects that. I think its nice, cosy, everyone seems friendly and I would've been fine there but depends on preference. The only thing is the flats are quite small in terms of size (max 6) so as long as you don't mind that (kitchens are also small).
I've heard mixed things about NB, its ensuite which if you really want is a bonus (rooms are quite small as a result tho), but people there don't tend to go out as much so you may have to branch out a bit more if thats what you're looking for. I don't think not being in North is the end of the world but its definitely added to uni for me.
Riverside seems relatively lively and is close to loads of things in the city (same for NB really) and think the rooms are generally ok.
