In their respective sports I think their is no comparison. tiger also did fantastic in his rookie season I guess only time will tell.

They both have the same mind set and determination thought that seperates champions from journey persons.

Always striving for new heights, always asking questions of themselves and their teams around them. At the moment hands down TIGER. But with modern day technology of equipment and caoching etc you have to equate it to Nicklaus and Hogan being also maybe quite as equal!!
