not really, I like them all for very different reasons-
I like Campbell's because of their faces, although they can be quite nasty..
I like Winter Whites, well my ones as they are like golf balls, little round lumps, although I often get heavily penalized for it.. I like their shape, especially the males
I like Chinese as they are quite sweet natured, although the look quite mousy, but I have mice so it doesn't make a difference to me
I like Roborovski as they are small. I have quite a few from one line which are reasonably tame, so they are quite cuddly, which makes a difference to how I feel about them
I like Syrians as they are bigger and I have more success with these, and I like the rare colours...
