I hate brady and I think he is cocky and his team is disrespectful. And he aint even a QB he is a a hollywood pesonality because thats all he cares about. But anyways the more accurate and more efficient one in my opnion is Manning.
Not really Manning is a better QB overall. Its just Brady plays good in the postseason but sometimes he aint that great in the season. I know the postseason is all that matters but Manning has a better vision and better accuracy and can read defenses and audible better. So if you forget about the postseason and regular seasons and just go head to head between QB's Manning wins IMO.
