It's been 10 years, so I don't really know the state of things these days, but...
I liked Friley because it was generally closer to most of campus, the library, and to campustown. Plus there was always someone up and around in Friley so it was hard to feel lonely or isolated or anything like that. Made lots of friends. Always something going on and such.
Had some friends in Old RCA, I remember their rooms being pretty big (Linden comes to mind... I think there were a couple of triples-as-doubles), and being closer to Leid/JTS/Hilton would've been nice.
Suites were new back then, I think just Eaton maybe. Nice and new, but seemed small.
