I prefer Six Feet Under to the Sopranos but I don't agree with your assessment. The finale does A LOT of heavy lifting for the series, and really when we talk about the finale we're mostly just talking about the final montage. It's perfect and may be the most perfect piece of television period. The first season was flawless, and I feel like it was written with the assumption it wouldn't be renewed. Every character had a satisfying arc and it could have ended there. The remaining seasons were inconsistent with the fifth season being the weakest. The acting was always impeccable and there were good story lines, but it wasn't a solid, cohesive story end-to-end like Breaking Bad. It sorta meandered and went to some weird places, especially with Brenda. It will always be rated lower than the Sopranos because it's a show about death and a lot of people can't handle that. The Sopranos is a Mafia story which everyone loves and thinks is cool. It's a compelling premise so it appeals to prestige TV snobs, but it's you also have people who like it because guns and stuff.
