Sopranos season 4 or The Shield?

[MenacingMonk]

Help me out of this dilemma. I recently bought the Shield complete series, but I still haven't finished the Sopranos box set. What should I do? A part of me wants to finish up Sopranos, but the other wants to start the Shield.

EDIT: Messed up by putting season 3 in the poll, but it's season 4.

I think shows are better enjoyed with at least some downtime between seasons...so I vote The Shield
