I like Eli354's the best, for sheer display of information. Gives a good idea of what I'm going to find in the Community Creations, if I happened to not know beforehand.
Go with spoonfork's. Sure eli's has more of a minecraft theme but it doesn't really yell "Community". Hell, Just take that banner and replace the words and use it for something else minecraft related. But spoonfork's actually has builds made by the community on the banner.
I like elegance in simplicity. So i really love luus's.
It also doesn't showcase anything, therefore not defining what minecraft is and i think that's the essence of minecraft, it's what YOU make of it. It really fits the best imho. It's just the essence, in an elegant and creative form. Love it.
Incredible job everyone.
Also, it seems that CorruptAngel has some mobs from here http://ghostfire.deviantart.com/art/Lil-Minecraft-Monsters-262373919
