Why are cats better than dogs?
First, let me say that the question represents my own, personal, subjective opinion.  I also adore dogs, just not as much as cats.  I am fully a cat person.
The cat, though.  I am humbled by the task of trying to accurately capture in words the mystery of these beautiful creatures who have chosen to enslave humans.  So instead, because I am also trying to train a model, I will just use a lot of unnecessary adjectives and that will have to do.
Cats have been around humans for a long long time.  I remember as a kid having a book that talked about how in Ancient Egypt cats were revered as holy creatures and kept in luxury in temples of Baast.  The first known evidence of cat domestication is the excavation of a Neolithic grave in Cyprus.  The thing I adore about cats is that they basically haven’t bothered to change themselves since then.  They just carried on being slightly aloof and mysterious, but also affectionate and playful when they feel like it.  And imperious and demanding, of course.  
Cats are incredible communicators.  They have learned to meow at humans because they realised we respond to meows, even though you will very rarely hear a cat meow at another cat (the indignity!).  Meows and chirps are the special condescending language cats developed to communicate with an inferior species.  My own cat can make crystal clear what he wants with looks, body language and the odd meow when he can be bothered.  He is also a total drama queen and obviously manipulative.  If he wants food he will try the ‘I’m hungry’ meow first and if that doesn’t work we get the full on “I’m starving, this is a tragedy, I will die almost immediately if I don’t get food right now”.  I am full of respect for the cats’ ability to manipulate humans and the shamelessness with which they do this.
Cats are also super independent compared to dogs.  No need for walks, no need for the dreaded poo bags, no need for expensive care every time you want to go away for a night.  They love their humans but 100% on their own terms.  
Cats are adorable and cute.  I can’t stress this enough.  Ever seen a cat roll over so you can see its fluffy belly.  How can you not melt.  Ever had a cat make biscuits on your lap (or in the air).  Cuteness overload.  They are even cute when they are mad.  And most cats I’ve met know how to gently tell you what affection is allowed and what isn’t (illegal belly rubs).  They will bat you with a paw, but the claws will be in.  And a cat purring on your lap is the single most relaxing thing in the whole world.
The Swedish word for ‘cat’ is ‘kattepus’.  That in itself seems a really great reason why cats are better than dogs.
The last word goes to Terry Pratchett, author of the Discworld novels, who wrote ‘In ancient times cats were worshipped as gods; they have not forgotten this’.  And neither should we.
