depends who you ask really. MJ is bigger, meant more b/c he was more creative and overall talent. plus he had his global massive fanbase through his career.
and none has sold 1 billion records lol
Most weeks at number 1: 1st place is Elvis with 79; 2nd is Beatles with 59 (edit: oh wait no, rihanna beat them this year). Michael comes in 6th, with 37.
Most #1 singles: Beatles are 1st with 20; Elvis is tied for 2nd with 18; Michael is 4th with 13.
i think that michael was much more global than elvis though.
