If you can afford the steep prices for club seats, I say go for it. I sat in 344 thanks to an invite from a friend who is actually pretty high up at Bank of America, so he get's these seats at his disposal. It's sickening how much better the game can be watched from here. The seats are only a little bigger than what you will find in the 100s and 500s but not a whole lot bigger. The leg space is more favorable but the seats weren't padded, just regular seats. The hospitality suites are a completely different story altogether, those seats were nice.
There were roughly 20 rows in our section so don't expect a tiny seating area; there are still plenty of fans around but you won't have nearly as much of a wait for the restrooms and at the concession stands. The club area is also much cleaner and was equipped with what seemed like more staff to help you find your seats, find the nearest exit, etc. You can't go wrong with 344. Enjoy the game!
