There's more story/quest content in tTK, but they have really messed up the end game - to the point that it feels like there isn't much of an end game worth playing... KF is a fun raid, but with no elemental primaries - and generally lacklustre gear overall - there doesn't seem much point in re-playing content. Add to that the fact that PvP matchmaking is immensely frustrating if you're a solo Crucible player, and I struggle to find a reason to play. Worse still, the lack of clear plans regarding future content means that, whereas with vanilla I wanted to keep my toe in to stay interested for the next DLC - there's no incentive to do so this time around.
