Both look great, I've personally gone for white rose because it's established but if I get put in carlton I'd be happy. It has loads to offer and roof terraces etc.. yeah, its a new accommodation so it's hard to tell how social it will be but it is as social as you make it at the end of the day. With it being new I'm guessing it won't be oversubscribed so you're more likely to get it if you do put it as your first choice though. At the end of the day make your decision based on affordability and what is highest on your list of priorities ( location etc..) the social aspect varies year to year.
