Ali is easily the toughest, followed by Holyfield imo.

Easiest is Dempsey or Tyson.

If you're including alphabet fighters, the Klitschko's win this hands down. I don't think vitali has ever defeated a top 200 Heavyweight( not even past their prime) and Wlad has Byrd, rahman(shot) & Mercer(beyond shot) as his signature opponents. Combined, their resumes suck.

- Not nearly so much as your top 200 heavy list that you wisely chose not to include to save us howls of derision........ 8)
