Well, that's a pretty stupid comic. Some dogs really only like their owner. Some cats are very personable and want to be touched all the time. Some dogs are friendly with everyone they meet but still give their owner special treatment as the alpha. Some cats love to swim, play fetch, and play with their owner in the wee hours of the morning. Some cats are jerks. Some dogs are jerks. Some cats act like 'dogs'. Some dogs act like 'cats'.
Neither is better, neither is worse, they're just two different animals and can't be compared to one another as they're completely different species.
Cat people and dog people are both wrong. The only people who are right are people who like both.
