I feel Both Deserve the privelege of Having ATG by their names.

Floyd Mayweather Jr.: One of the most technically skilled fighters of all Time. His education in the fistic arts is unrivalled by anyone save perhaps Pernell Whittaker. His impeccable record is a representation of his brillance and his opposition cannot be deemed anything other than high. Although not a fighter of immense popularity he will be remembered as the best Fighter of this generation who's tactical boxing was supported by a master plan which took over two decades to formulate and constant practice to perfect. This style will allow him to fight on as long as he wishes, without his body failing him as each fight merely adds to his depth of expierience and ring knowledge.

Roy Jones Jr.: When viewed next to Mayweather Jr. one realises Jones was not the perfect boxer. However he was for a period of time the perfect fighter, His physical ability was the equivalent of Mayweathers boxing ability and he used it to tremendous effect in his prime. His opposition cannot be depicted as the greatest, but one must remember it was not who he beat (although there are some great names there,) it is the nature of the beatings he administered. Jones had the ability to humiliate an opponent by revealing an opponents shortcomings in comparison to his own and then delivering a perfectly timed display of his own supremacy. The losses on his record are a resultant of the body's natural deterioration as a result of time and unfortunately unlike Myweather he never had the polished skills or Ring knowledge to fall back on that Floyd will.
