It's like with everything else: People have different preferences. Some brands have distinct sounds, usually a result of the bracing they use, and I think it's fortunate that you have a clear preference as that makes purchase decisions much easier. (I feel that individual instruments even by the same maker sound different and I doubt I would be able to distinguish different brands in a blind test, except maybe for KoAloha.)
