It's actually pretty crazy how close these 2 dynasties have been from the numbers. I think NE gets a plus for doing it in the salary cap era. If they can get another 2 years out of Brady with 11-12 wins and no Superbowls we're looking at almost identical numbers. I was too young to catch the first 7 or 8 years of the 49ers dynasty but it felt like growing up (with a not great Pats team to watch) that they were always beating everyone.49ers won 5, too.

They are pretty similar, but New England does seem to have a little bit of an advantage. I wonder how things might come out when considering SOS and differences in the league (# of teams, # of available playoff spots, etc.).
One thing that's pretty interesting is 3 of Montana's playoff losses were against Belichick's defense where he scored a total of 19 points. He beat the Giants a few times too. But it's funny that without Belichick that 49ers dynasty might be sitting at a few more titles.
