I loveeee Speckled Sussex, and pretty much any Top Hat Breeds - out of the Top Hats I think the Appenzeller Spitzhauben is my favorite, then Polish, and Houdan.
EEs are fun for their range of colors.....its hard I have to say its hard not to love them all!
The smaller list maybe my least favorite, I have some white leghorns that are extremely flighty and had brown leghorns the same way, So I would say they are my least favorite personality wise, but they are excellent layers..
