I liked the early days of the brand split when Smackdown was the workhorse brand led by Brock, Angle, Benoit, Guerrero. Raw was more storyline driven led by HHH, Michaels, Jericho, Kane. I liked the dynamics of Raw and SD and how it's similar to leagues with different conferences. NFC/AFC in the NFL and AL/NL in baseball. The beginning of the end was when they kept moving key pieces of SD's workhorse image. First Matt Hardy then Benoit and Edge. They gave SD Booker T and RVD who were good workers but were stale at that point. The brand split had its moments but Vince wasn't patient enough to let it reach its true potential.
