Planning a trip to an NFL game in 2012: where should I go?

So I live in Southern California. My goal for next year is to go to an NFL game. I've been to Candlestick in San Francisco as well as Qualcomm in San Diego to see games. I'd like to travel out of state (Sorry Raiders) to go see a home NFL game. My question is: which one? Which stadium has an enjoyable feel to its home games? Where will it be fun? I'm not picky to any team. Any suggestions from r/NFL on where to go?
