Have you played the job quests?
I'd say many of them are very shallow and have no room to breathe. SAM from 60 to 70 was boring. Every WHM quest is painfully generic. You can't tell a decent story in the odd 5 quests or so you get from old cap to new.

The ShB option is the way to go. They tell a way, way better story, are interconnected and more than the sum of their parts on top of a nice incentive to play different roles to see all aspects of it. I'm more than happy we get that.
