The Delonte comparison holds up okay, Manu is just a much better player.

Manu is a tough compare since he came in polished, both DA and West have had to season. West's got more TOs and more athleticism (rebounding and blocks), DA gets the edge with the shooting and efficiency.
For now I'd say West. Jameer and DA compare favorably, except Jameer's stats are skewed by the high utilization of being primary ball handler. Which gets back to why I like the West/Ainge comparison - they are both better as a combo guard role / non-primary ball handler, but capable when called in to bring the ball up.
