I love black moors. I like the stream-lined ones with a flowing tail and appropriate sized eyes. They have always just appealed to me, maybe it's because they are one of the few goldfish that will stay black (or at least have a better chance at staying black over others). Second would have to be a red capped oranda, since my first goldfish I owned was a red capped oranda named Willy Wonka. Third would have to be any kind of calico goldfish. I love the calio coloring!
