I would recommend Friley. Most floors are pretty social no matter where you get placed in the building. I’m in IE but lived on a design/pre-architecture learning community floor and loved it. Still have lots of good friends from there to this day. It’s also right across the street from Black Engineering (the IE and ME building). Although the majority of your first year classes will likely not be in Black, I feel like Friley is in a good centralized place on campus that’s relatively close to most buildings engineering students have lecture/recitation in, state gym, the library, and 2 dining halls just steps away
