Stevie Nicks or Janis Joplin?

[Villavic]

I have read in some articles about Stevie she was mentioned as the "new Janis Joplin" in some moment. But.. who was greater artist, Stevie or Janis? I think Janis is qualified as a LEGEND cause she was "lucky" to die young, of drugs overdose (something stupid imho but all of them, Morrison, Hendrix, etc who died young are legends in part because of that, I even read sometime that they don't forgive Bob Dylan of being still alive , so stupid)

And Stevie's carrier is logically longer than Janis'. Ok, it's not a matter of time, it is talent, the voice, etc,.. I know that.
So.. answering not as a fan but being as objective as you can.. who was better.. Stevie or Janis?? I think Stevie Nicks is greater, anyway.
