Like so many great young talents Anthony Kim needs to grow up. Where Tiger was mature way beyond his years, and was a top-notch professional right from the start, Kim is 180 degrees his opposite. Out partying all the time, drinking and missing practice rounds/showing up late.
Maybe he'll grow up soon, but if you don't like Woods' personality, you sure wouldn't like Kim's. Actually, I take that back. Kim is a "fun" guy. Probably everyone around him likes being around him, but he doesn't take his work as serious as Woods.
If he had the drive that Woods does, Kim has all the talent in the world, and could certainly compete with Woods.
