United Center crowds for Blackhawks games can be raucous, I always feel a sense of danger when I attend a Hawks game against a rivalry like the Detroit Red Wings or Minnesota Wild.
It's kind of like a fight can break out from nowhere with little to no notice, especially in the 300 levels. And fights do happen up there with a lot of frequency.

Anyway, the best seats in the house, in my opinion are at center ice. You can sit in the 100, 200 or 300 levels at center ice and be fine. The 200 level might be the best view, but 331 certainly is right up there in terms of good views and is much cheaper than other sections at the United Center.
