At Boston Garden, it goes (from top to bottom) Balcony, Stadium, and Loge. Unfortunately, in hockey, there are plenty of obstructed views as you get lower in the loge section. The plexiglass inhibits your sightlines in at least one corner when you are in the first 10 rows.
The best part about the loge is that the hockey fights are right in front of you. They are cool to watch on TV, but they are awsome and sometimes scary right in front of you live.
