Cat lovers or Dog lovers: Who Rules?

I found this very beautiful cat looking back through the rocks, possibly in case one of his bretheren were about to pounce. So I've been having this conversation over whether cats or dogs are better. Here's a little something to get you started. For cats: smell better, good groomers, can be left alone, smarter (???); for dogs: faithful to a fault, always happy to see you, will go running with you. Against cats: can be aloof, can pack a nasty paw, chock full of allergens; Against dogs: more maintenance, smelly when wet, can be hyper. What do you think? Do the cats have it? Or do the dogs?
