My favorites (unless you're letting me sit in suites or in the club) would be the upper 100s. When I was a kid, my grandparents took me a game where we were at the lower 100s on a sideline and we had a hard time seeing over the players.
The upper seats are indeed steep and I was just in 631 (first time I've been terrace level in many years) for the Bucs game. The main caveat there is if you have bad knees (I have arthritis in my right knee), those stairs can be a (literal) pain going up and down.
