Would you say Avril Lavigne is as influential of an artist as say, Eminem?

I think there was a time when Avril had more influence but Eminem is much bigger than she is right now. She has a good message but she doesn't have enough fans to really make as much of a difference. An argument could be made that Eminem is in the hight/peek of his career. Avril reached her peek in her first album and really hasn't been as big since.
