Never have been either.
The 3 4 is very weak against the pass happy teams in the NFL now.
You either have 4 run stopping pass rushing studs on the line or you're in a world of hurt against the most elite passing teams like us, the Colts and the Saints.
I always have thought the 4 3 was the best defense and still believe it is.
I'd love to agree with you but when 6 of the last 10 SBs were won by 3-4 teams and the others were won by teams with cover 2 defenses and top tier pass rushing ends (Dockett and Campbell have not proven to be close to Mathis and Freeney in this regard), it makes it awfully difficult to agree. Good 3-4s don't get torched in the passing game because they have good pass rushing OLBs, not 32-34 year old retreads.
