Regarding Brady - I didn't mean to paint the picture that he is some chump. But to say he is better than Manning because his team has won Super Bowls is, at least in my mind, not right. You have to look at what was done on the field. And when we look at what was done on the field, I'm pretty sure Matt Cassel managed that record breaking offense to 11-5. If a player is that important to his team - and that GREAT of a player - they do not replace him and go 11-5. I know it is a drop from 16-0, but come on. Look at the Steelers without Polamalu - they don't make the playoffs. To me that is an MVP, a truly great player for his team.
On that same note, lets look at when Ben got hurt and Dennis Dixon almost leads them to a win in a game with massive playoff implications in Baltimore. I understand the Super Bowl victory is so important to a resume, and clutch performances are huge on the resume. Peyton led 7 4th quarter comebacks this season. That is a pretty damn efficient 2 minute drill. Yes, he came up short at that critical moment, and I know a lot of people who say one moment defines a career and all that BS. A career is a career and watching many QBs play, Manning shows a game knowledge and ability that I haven't seen from anybody else. Yes, he made a critical mistake and has a team record of 9-9 in the playoffs. I'd still take him over Brady, Ben, Warner, Favre, Rodgers, any of the guys today. He is in the conversation with the rgeats as one of the best QBs ever - you could argue not one of the most clutch, but the conversation of best QBs, best at his job, he is hands down in that conversation with plenty of others already named in this thread. You can't name on guy the greatest, at least not that has been seen.
Also, that question - who would you take as your QB and everybody then qualifies it "for the super bowl" or "for a regular season game" or whatever - The best QB will be the one who is chosen as the QB to lead the franchise, through the whole thing. You don't pick and choose when you use your QB.
