Ok, first of everyone, he asked about the three most recent games in the series... Not Madden 99 or '04. Between 06, 07, and 08, 07 is the best in my opinion, but that is because I love to run the ball, and 07 was meant to be all about the running game. If you're a passer, go for 06, it was set up around the pass game and some of the features carried over into 07 but not all. Now if you love to play defense, 08 is the way to go, it has most of what 07 and 06 brought to the table but not all, because the defense was meant to control this game, it also has some new offensive pass features that can be fun but not needed. So in the end I would choose 07 because of the run game and the outstanding superstar mode which may be better in 08 but still just as good in 07.
