We are in the upper deck. We spent the first 10 years 28 rows up (5 rows from the top) on the 15 yard line. True "nose bleeds" but they were good seats.
Last year we moved our seats - still upper deck but 11 rows up and near mid-field. They are great seats. It is pretty much the same view you would get from a TV at home.. can see the whole field easily without having to follow the action with your head and can keep all in peripheral. The few times I have sat in the lower bowl or in the suites - I did not enjoy it as much because of the views aren't as good in my opinion.
Sound system absolutely sucks where we are though. Cannot hear it at all. It's like Charlie Brown's teacher. Have to watch the closed captioning.
