I don’t think one is better than the other, they’re just different and it depends on what you want out of an animal. I have a dog and two cats and they’re very well behaved, but I like my dog better. I like to go jogging and having her with me when I go is more fun. But dogs are also much less independent and require a lot of care, and cats in general are more into being cuddled than dogs are in my experience. Less active more introverted people seem to prefer cats, and that makes total sense to me.
