Hulk Hogan in terms of impact and drawing money. Ric Flair in terms of ring work, work ethic, influence, etc. Flair has probably influenced more people to become wrestlers and probably wrestled more hours of matches than anyone else has in history. But Hogan is more renown throughout the world than Flair is, especially in North America which was the primary location that both men worked in throughout their careers. And he undoubtedly drew more money overall than Flair did. Taking Hulk Hogan out of wrestling and leaving Ric Flair would leave a greater negative impact and not as much of a positive one than taking Ric Flair out of wrestling and leaving Hulk Hogan would. Thus, the answer to me is Hulk Hogan.
