I have Rexes, Brazilians, and Californians. Rexes are my favorite for fur, Brazilians for temperament. Californians are utilitarian--can't say they're a favorite, but they serve a useful purpose in my rabbitry.
I love the coloring of the Harlies, but I would be perfectly happy with a harlie-colored Rex.
I love the idea of wool breeds, maybe French Angora, but I don't think I could ever be in a position to put the time in to care for them. I guess I'll just have to find a wool-breed raiser or two who is willing to trade wool for meat or pelts or something.
