I'm only 17 so I was just a wee tot when big brother started but I think I have pretty good understanding of the winners. This list is based on gameplay
PS I'm not super educated in the earlier seasons
jesse2014 I disagree quite a bit on that, I agree that Dick and Rachel so much better TV than Andy and Maggie. But gameplay wise they are such better players. Dick would have been gone first in the jury if it was not for americas player that saved his ass. Also Rachel would have been gone if not for the first ever pandoras box that actually did something in the game giving them a team veto and giving Rachel the exact same challenge that she already won, giving her and her #1 ally (jordan) off the block. Twist saved there games.
While Andy played a great game, got into the majority. Flipped when he needed to, the Double eviction with Amanda and Elise going out was a thing of beauty. Won challenges down the stretch and got to bring the Goat (Gina Mari) to the end. Boring yes but great.
Now Maggie was also a great player she lead a big alliance (hated) all the way down to the win. She was Derrick before Derrick. The reason why she was hated is because the friendship had so many dislikable players. Also she went up against fan favorites and she won. Now is she fun to watch no but gameplay wise a great player.
