In their prime, who was better, Charles Barkley or Elgin Baylor?

Now, before you start telling me that these two were completely different players, let me explain some things. First, they were roughly the same height (around 6'5) and were explosive offensive players who were known for their thunderous dunks and rebounding abilities and overall well-rounded offensive game. Charles played the power forward position and actually Elgin did too, although most people would think he played small forward. Barkley was much bigger than Baylor but both were known to be very strong physically. Defensively, neither were known for their great defense but Barkley was known for his aggressive play, while Wilt Chamberlain wrote in his autobiography that Elgin did not play defense but rather "waited to play offense again" between posessions. So, in the end, who is the greater player overall?
