I dunno. Prior to Jean getting murked the 2nd time by Xorn, it was said that she and the Phoenix Force were one in the same.
Now, X-Men Warsong and Endsong and then of course, AvX...they ALL came along and fucked up the continuity of the Phoenix Force period.
Wanda after Children's Crusade and that whole Life Force shit, she really became way overpowered.
I still say that Jean/Phoenix curb stomps Wanda easily.
I can't say that I know anything about DC's Raven character.
