In my opinion, lower level seats in the 100 sections between the 40's at least 15 rows back but not more than 30 rows back is the best (non suite) seats in the house. Any lower and you can't see all the action.
Good lick with the Pats tix, they seem to be the priceist tickets online off all season, and I was going to fly in from Los Angeles for that game as it's near my birthday.
I am in section 513 and my wife and I was looking at the lower section below ours before the game last week. After talking to several of the ticket holders from down there I will keep my seats over theirs. They told us the view was not that much greater in their section compared to the extra $$$ they cost.
'79-'91 - grew up sitting in Sect. 639 (midfield terrace) for Saints and Tulane games. Wide view, learned the game
'92-'05 - moved to Sect. 119 (10 yd. line, visitor' side 15 rows up) partied, chased tail, close to the action
'06 -present - Sect. 123 2nd row, Seats 1&2 above end zone "Emergency Exit " sign, visitors side -perfect perspective, can see holes open, pass patterns develop, awesome view of Saints sideline, players and refs can sometimes hear you, can get rockin' pics.
Have been invited to club and suite level many times, of course those rule.
Without a doubt, the sideline Club Level (formerly LOGE level) seats are the best in the house. While the top rows of the the sideline Plaza level are not bad, they are a little low-- you're not high enough to see what may be occurring towards the end zones. Also, the angle/grade of seating in the Plaza is too gradual. Think an old-time movie theater compared to the new "stadium seating" theaters.... Lower level terrace seats are not bad, but to me they are a little too far from the action, due to the two levels of suites between the terrace and club levels.
