#1 hw is a toss up between louis and ali.........

i really cant decide though i am leaning towards ali due to way better competition even though louis reigned for so long.

they are both great champs but i probably see it like this.............top 5
#1...ALI
#2...LOUIS
#3...TYSON
#4...LEWIS
#5...FRAZIER,JOHNSON,LISTON,FOREMAN,HOLMES....TIED , cause i cant make up my mind on #5

but i wouldnt put marciano in top #5 just cause he fought shit opposition .

....and every one of these fighters i mentioned would beat him PRIME 4 PRIME
