Out of those three you've mentioned I would say the Lesser Sulphur Crested to be the better pick! My Dixie is a Lesser Sulphur Crested and she's the sweetest bird ever! Just do understand what everyone else says is true about Cockatoos as they're not just a bird for anyone to handle, they can be problematic. IF you do ever decide to get a Lesser Sulphur Crested, just make sure you care for it right as they're a critically endangered specie. IF I must one day, I would give Dixie up to them for the purpose of breeding to preserve their specie. I love her enough to know that's the best thing to do for their specie.
