Depends stongly on what you consider a good paladin UI to have. I am a paladin and I create my own, so all the pieces are directed toward what I find important, which is mostly keeping things out of the way and allow me to actually see the game, while keeping the relevant data present.

But I wouldn't make the claim that its a hardcore paladin UI by any means, just used primarily by a paladin.
