340 is great! Even though you're on the 30/35, it still feels very much like it's on the 50 because that high up, you feel close to all parts of the field. There are a few downsides. 1) Being far from the field just takes away from the experience. 2) Getting to the upper level via the escalators is always a challenge and leaving the stadium is just as big. It takes some time. Even though I was a fan of the old Giant stadium, Metlife is beginning to grow on me with every Giants game I attend. I wouldn't dare attempt to attend a Jets game at this place but that's how deep my devotion to this team is.
I always sit on the upper deck. The ticket savings it provides allows me to see a higher volume of games each season. Love that they provide fans with tvs all over the concourse area. The upper level concourses don't allow for as good of a crowd flow so the lines for the food/beer are typically longer.
