re: Rank These....

It's really all about individual tastes. Mad Men is the most thought provoking of all 4, with slot of what makes it so good being beneath the surface. That being said if you have trouble getting into any of the 4 it'll be Mad Men. Suits is awesome but it's a much different category of show than the other 3 and the wire. The other 4 are consensus best tv dramas of all time. Breaking Bad and sopranos pretty much comes down to what premise strikes you as more interesting. Personally I'd give a slight edge to breaking bad for originality, but sopranos is on hbo which means more cursing, violence, nudity.

Side note: mad men would've been legendary on hbo
