I've been to the Consol twice since it's birth (haha) One time was for a Pens game and the other was for Disney on Ice this past weekend. Both times, I bought tickets at the last minute and ended up on the 2nd floor in the 200's. While it might seem like a crappy section, there legit is not a bad seat in the house. Actually on the 2nd floor, you look RIGHT over the stage/ice/ect.
As for the building itself, it's very spacious and modern as others have pointed out. There are multiple entrances so the line moves pretty fast to get it.
I wish I could do a compare/contrast with the Igloo, but I was extremely young when I visited there.
However, all good things must come to an end. The Consol works for me. I'll add pictures sometime later for proof that view all around is decent no matter where you are!
