Where does Lennox Lewis rate in your all-time great heavyweights list?

I personally rank Lewis in my top 10 around #9 or #10. I think he was very good and beat some good fighters. I am a believer that beating a good 230 lbs. boxer counts more than beating a good 190 lbs. boxer. So, some of the old-time heavyweights' victories don't count as much as Lewis's. He was only beaten twice and avenged both of those losses. He beat all-time greats Tyson and Holyfield. He beat a lot of the top contenders of the 1990's and early 2000's: Tommy Morrison, Ray Mercer, Razor Ruddock, Tony Tucker, Andrew Golota, Shannon Briggs, Frank Bruno, Vitaly Klitchko....He was more dominant than Holyfield was. Where do you rank him?
