All list are subjective. For anyone that does not know the meaning of the word, here is the explanation Subjectivity - Wikipedia, the free encyclopedia

Every list is going to be an opinion that is subjective. If I were to pick a fight that was a legitimate draw and I'd follow one fighter more than the other, I most likely would pick the fighter I followed as the winner. Example: Marquez / Pacquiao I.

I would be interested in seeing a comprehensive list that was based on a point system like BoxRec Ratings Description - Boxrec Boxing Encyclopaedia

There are things to consider that can only be subjective. They are not calculated into Boxrec's formula i.e. When fighters go past their prime and a lesser fighter wins. When a fighter fails to defend his title against other top rated fighters. When a fight is killed in the ring... (nah... forget that one) Fighters may have had injuries or had been weight drained. Anyway you get the point...
