Went to the Giants-Packers game back in November. 334 is on the upper southwest side of the stadium, just past the back of the end zone. Most annoying part were the fans constantly walking up and down to and from their seats. You can avoid alot of that if your seats are in the first 4 or 5 rows. The seats aren't as wide here as the club seats but still comfortable and still offer a good bit of leg room. If you're a true Giants fan, 334 will be heaven for you - right with all of the other Giants die hards.
There were tons of Packers fans in our section who too decided to purchase the cheap seats. Didn't really see too many Giants fans giving them a hard time but I always feel for visiting fans that venture into this stadium. The Jets fans are usually much worse towards visitors though. And if you're in the mood to tailgate, parking passes are expensive but you can find them online ahead of time to save the headache. The NFL Ticket Exchange and Stubhub both sell them. Lots L, J and K are probably the best for regular patrons but require a little bit of a walk to the stadium.
