Never really used Prince and I'm not familiar with any of his work so I go with Freddy by default.
But I absolutely love Queen's music and Freddy was so intriguing to watch doing his thing on stage.
So sad he died so soon, such a talented man with amazing vocals.
This is tough, both are insanely talented. I think Freddie though....one of the best voices of all time IMO, and his stage presence/charisma was unmatched.
