Neurosurgery VS. Cardiothoracic Surgery?

I would appreciate if someone could elaborate upon the differences between these specialties regarding lifestyle, residency, variety of procedures, and future of the specialty? I'm equally interested in both fields so far in terms of the organ systems and procedures. Just wondering what others think. Thanks!
