That depends on your definition of the word "successful." If you mean which group is more numerous and has populated more of the world, it would be the invertebrates. If you mean which has more higher intelligence, it would be vertebrates. If you mean which group is more essential to the food chain, it would be the invertebrates. If you mean which has the largest animals, it would be the vertebrates. It all depends on what you're talking about.
