I just finished the dark bortherhood questline for the first time. It also has a good quest line, however, it felt like an extension of the thieves guild more than a section per se. This is encouraged by the fact you are sent to the Thieves Guild a couple times while in the Dark Brotherhood.

I have to say the it was the fact you don't have to kill, in fact, it fails some missions to kill a target. Dark Brotherhood, I feel, is a place you can go to if you want to use your assassion skills, but only in conjunction with the thieves guild.
