How do you rank the seasons? My ranking:

6B > 5 > 2 > 3 > 4 > 6A > 1

Every second of 6B is just top tier television.

Season 5 is incredible, I'll always remember sopranosautopsy.com's line "Season 5 holds a special place in my heart. I don’t know if it’s the “greatest” of the Sopranos’ seasons, I only know that it is my favorite."

Season 2 and 3 are kind of opposites for me in a way - season 2 has one of the best openers and arguably the best finale of the run, and has consistently high quality episodes throughout the entire season but maybe no other complete stand-out episodes. Season 3, on the other hand, might have the weakest opener and finale of any season, but is loaded with stand-out episodes in Employee of the Month, University, and of course Pine Barrens.
