I can't say which is better, if dogs or cats, but among them I prefer cats. I used to have both at home, so I could compare their behaviour and their way of reacting. I think cats are more... indipendent. They like to mind their own business and hate to be disturbed, but they're really funny, because in the end they're crazy and nonsensical animals, but they can be mysterious at the same time. And their selfishness is amazing
