Been field level several times, didn't like it, I like between the 30's, (closer to midfield obviously) a little bit up, looking down.
I'm a baseball freak, go all the time, my favorite seats at the stadium is 612 (behind home plate but upstairs) no obstructive view, every thing in play is in front of you looking down.
I prefer to tailgate at games, but would rather watch them on tv. It's fun to go and all, but you spend half of your time asking what you just missed and watching the replay. Don't get me wrong, going to the game and the environment is fun, but the best view is about 12 feet away on the couch. That being said when we do go to games I prefer to be about 10-15 rows up between the 20 and 30 yard line.
The major point is to be between the 20 yard lines.
You will want to be at least 12 to 15 rows up if you are on the lowest level.
Upper levels are fine. I think you can see plays develop a little better when you are up high, however the crowd noise isn't nearly as loud as the 1st level.
Tip - Bring a pair of binoculars no matter where you sit. Have fun!
thanks all! the reason i am considering the tickets are because i'm from asia, and gonna be in France for 2 years for work. figured this would be my best chance to catch a football game live.
