It 's tough to figure out who's the best but my top 5 in not particular order are Rodgers, Brady, Brees, Manning, Marino.
I've been fortunate to see all 5 play in person multiple times.
Only Brees didnt impress me but that was in his younger San Diego days.
With Rodgers, his "shiftiness" is QUITE impressive
With Brady, his "fastball" is impressive
Manning just had awesome command
I'm a dolphins fan, so i can write 1000000 about Marino.
Ironically enough, 1 of the greatest qb performances i've ever seen was Michael Vick. Guy looked like a video game qb out there (this was maybe his rookie year before we had many running qb's).
I've been to over 200 NFL games in my life and whenever i know a good qb is coming to town, i get really excited!!
