Adium X 0.86, a great unversial IM for Mac OS X

I cannot live without IM. That's why today I started looking around trying to find a Mac OS X app that does Universial IM. I found one from the site called Adium X 0.86 and boy it worked so well. I am using it now, and think that it looks much better than GAIM on PC. How come everything just look better on Mac :-> ?
