i love all cat's so it's hard to choose but i think i have a preference for cats who are one or two colors over many. Though there are exceptions (my sweet baby pi was a calico tabby of some kind and looked like smores... toasted marshmallow..)

grey, black, and white cats are probably my favorites. I think tuxedo cats are delightful but I think that if I were thinking of the platonic ideal of a tuxedo cat, it's a lot harder to pull off. High risk, high reward. Y'know? Most tuxedo cats are relatively unremarkable (Though all cats are the worlds specialest creatures. Please make no mistake.) but they have the benefit of having sock feet so they're kind of winning.
