Beyonce by far. Britney, at this point, is only "remembered' for negative aspects because those same negative aspects overshadows her "iconic" moments. Her peak was so short lived and she was NEVER taken serious as an artist to begin with, nor has she ever been highly respected by the general public or even music critics.
Beyonce will continue to go on to do great things while Britney will continue to decline and become a thing of the past.
