In 2003 my season tickets were in the Sun/Moon Deck 7 rows up in the middle of the row. 2004 - no season tickets... but last year I went once again with the Sun/Moon Deck but 1/2 way up and the last seat (so no one would bother me) right next to the visitor bullpen. This year as part of the Power Pack I got the Bleachers (first row).
If I had a preference for pricey seats it would be the first rows of the Sun/Moon Deck. But I'm pretty cheap so it's the last seat, top row on either side of the ballpark. The reasoning is that I don't want people bothering me when I'm watching a game... (having Chip around is OK...
Another reason for the above mentioned seats is that I'm short and the angle of the lower level seating (the higher priced) is such that if another person who is taller is sitting in front of me, the view is blocked. The company tickets, as wonderful as they are - Row 132 is a problem when there is taller people around.
