Honestly I had to chose who I'd rather see survive from that arc, I would have preferred to have Diadara killed off and Sasori continue to go on.

From what we've seen Diadara seems to be nothing more then a one trick pony.
Chiyo explained the culture of the sand village, and how the ninjas of sasori's era were raised to have no emotions and learn only to kill. Sasori's whole backstory is meant to be understood that he is a product of the environment he was raised in. I actually prefer his moments in the series more than most others because there was alot of depth in it without it actually being spoonfed like so many other aspects of the show.

I also like seeing fights where a major character is defeated before his abilities are fully utilized, just because its too cliche otherwise.

Edit: Also....kimimaro and haku had much less involved backstories too. Like them, I'm sure sasori's backstory will be twice as long in the anime than in the manga.
