The Cane Corso is a large and very powerful dog that can be quite aggressive. There have been multiple attacks some ending in death that have gotten a lot of media attention. This has gotten the breed banned in some places and has also made it very popular with other people.
Dog within a breed are NOT like boxes of cereal, they are NOT cookie cutter the same. You can't really learn about Cane Corso from a handful of anecdotal experience. Even if you could learn about the breed in general through a series of anecdotal stores, that wouldn't really have any bearing on the Cane Corso YOU would end up with.
It doesn't matter what the 'average' Cane Corso is like, what matters is what the parents of a specific Cane Corso are like, and how the dog was treated/raised/trained.
If you get your Cane Corso from a responsible breeder who has two well adjusted good temperament dogs, who does all the early exposures and training, and when handed off to you, you continue with proper socialization, good training, etc , you will have a great dog regardless of the breed's reputation. You can basically insert any breed in the above sentence and get the same end result. 2 well tempered parents plus good socialization and training = great dog regardless of reputation.
But even in the above scenario, if anything ever goes wrong (your dog gets attacked at dog park by another dog and simply defends himself for instance) because you have a breed with a bad reputation your dog is going to automatically get 100% of the blame.
If you are handed the same pup but you fail on your end you will end up with a disaster, and unlike a yorkie disaster, your disaster has the power to do tons of damage.
Similarly, if you get your Cane Corso from a breeder who is enamored with the 'bad-ass-nature' of the breed who has very aggressive parents, even if you and he both do great training and socialization, at best you have a mixed bag. Get off-track and you again have a disaster.
In sum, you are looking in the wrong place for answers, and you are asking the wrong questions. Look at breeders, look at the dogs they are producing and how those dogs are. It really doesn't matter what the rest of the Cane Corsos in this world are doing.
Note I would have an entirely different response if you were to say 'Hey let's all share stories about how great these dogs are" but it doesn't sound like you are just after stories, it sounds like you are after information to help you make a decision.
