It's impossible to go wrong with seats in section 500 for Ravens games. We were right on the 50 and on the same sideline as the Steelers bench. (Yes, I made the trip to Baltimore from Pittsburgh which isn't a bad drive at all.)
You can easily see both jumbo trons from section 500, to your right or left, though I wish they were located at the top of the stadium rather than at the bottom. There are 26 rows in section 500 as well as most of the sections in the top deck as a reminder. Our seats in row 3 were amazing; we had no stairs to climb and quick access to the concourses since the exit tunnel was at the foot of the section.

If you're willing to walk a few blocks, I recommend parking at the garage on Howard Street next to the arena because it is a bit cheaper than parking closer to M&T Bank stadium. You can also avoid a lot of the traffic congestion after the game by parking further away. Unless you're planning on leaving early or waiting in line for 2-3 hours after the game, avoid riding the Light Rail because there will be just too many fans trying to get on it.
