The general consensus of expert opinion seems to be that it was either Sugar Ray Robinson or Muhammed Ali.
Other very popular opinions include Rocky Marciano and Joe Louis, but, then again, the popular thought is also that had Mike Tyson kept away from drugs, he might have also proved a strong contender.
The best Asian boxer is Manny Pacquiao because he holds seven world titles; he has more titles than Floyd Mayweather jr. but I sill think Muhammad Ali is better than Pacquiao. Ali could have held several titles like Pacquiao but he started off as a heavy weight, which is why he only held 1-2 titles. The greatest boxer right now is Gennady Golovkin because he is undefeated, 35-0 with 32 knockouts. He has the longest knockout streak in Middleweight history , winning 22 of his last fights by knockout. He's beaten world class contenders and former champions like Curtis Stevens, David Lemiuex, Marco Antonio Rubio and Nobuhiro Ishida.
