I thought Daemon and Freedom were better, (but you have to read them both! It's more one book than two.) but Kill Decision does have some interesting points to it.
They were definitely better. I'm decently sure that Suarez had a few great ideas, and a wrote his first book using the best one, and was then on the hook for more books.
Edit: Oh! If you liked Daemon, check out Nexus. Same "problem", different core tech solution.
