Funny, most papers you read attribute our (Homo Sapiens) survival to being smarter, but I'm not convinced that was necessarily the case. Perhaps the Neanderthals succumbed to a particular disease that Homo Sapiens were able to survive. With their bigger brains, Neanderthals could have been smarter than Homo Sapiens. The areas where Neanderthals lived and interbred are more developed and have more advanced cultures than those that had no contact. Sub Saharan Africans have no Neanderthal genes and also are the least developed societies.
