Agreed on all counts, but Odom is also worlds better defensively. Kukoc was a sieve, while Odom is very good both individually and team-wise, and a very versatile defender to boot.
I think you're overrating Odom's defense a bit, he's decent, I wouldn't say he's anything more.
Odom's better though. Above average teams have been built around Odom. I believe that given the right coach, he can be the centerpiece of a contender. (Mainly because I think he would respond to all that responsibility and trust like he isn't doing with the constant suppression he's getting in LA). If Dirk can why not Odom? Not saying he's as good, but he could be, and nobody's tried it yet.
