Went to UCR, lived in each dorm in various settings.
Each complex has a different atmosphere alright. If you plan to go here, plan accordingly.
Aberdeen/Inverness ResHall
Pro - good social, large study areas
Con - oldest, cannot control climate control. Smallest desks. 3 person "loft" room is bad layout.
Lothian ResHall
Pro - Newer (Eastside)
Con - crowded, worse parking
Pentland Hills
Pro - Newest. Private shower and toilet/sink areas. Comfortable lounges, suite living.
Con - Gas leak smells(old side), longest walk to campus (5 minutes) of any dorm. Arrogant rich kids live here.
But go for dorms, you meet people. Thats the only useful function I can think of. This BS about "higher grades in dorms", ha. I got worse grades ever in dorms. Plenty of interaction of people if you know what I mean.
