I have quite a few favorites, some that I like okay, and find many breeds to be unappealing in looks (but still great rabbits in personality, actually usually nicer than my favorite breeds whom tend to be high strung!)
Among my favorites are English Spots, Belgian Hares, Tans, Britannia Petites, and Himalayans. I love that long body and thin, sleek look. I enjoy the high energy of these rabbits, and appreciate the great temperament of the Himalayan.
I like Dutch's, rexes, Checkared giants, Rhinelanders, etc a lot too, but they don't make the favorite cut. I love how sweet my Dutch's are, and I don't know much about the other breeds other than at shows I always are looking at them.
I am not a huge lop fan (I think they look odd, but appreciate that they make great companions) but my exception to that is the English Lop -- I think they're seriously cool critters and I was happy to see one in real life at a local show.
I also think Angoras look funny but they are the nicest feeling things on the planet! At the show I couldn't stop petting them! I wanted to cuddle with one, but I have a feeling that would not only tick off the rabbit, but the owner who had been grooming it all day!
