You know, I am not sure that there is. I can... count I think three times that Jean Grey has come back? (Originally with X-Factor, then twice after that... but she's currently still "dead").
Where as Mac... I believe there's about four times, right off the top of my head, I believe if I am remembering correctly... (counting this most recent one).
And on that note, an interesting thread on another forum.
Jean's only died 'for realsies' twice, the high-profile nature of her first resurrection and her Phoenix powers tends to give her a label as a resurrection queen that just isn't warranted. She died on the moon in the Dark Phoenix Saga, that was later retconned into not actually being her, and then she was never actually killed off again until she was killed by Xorn/Magneto in Morrison's run. She came back from that death in Phoenix Endsong, and she's currently chilling in another plane of existence, waiting until she's ready to come back to Earth.
Not counting all the one-off deaths that every hero racks up, Jean has only died twice. And she's not currently dead, just in character limbo. Mac's got her beat.
Suzene, nice Python bit there.
Depends on how you count it. As a reader, I don't care how they retcon it - I care about how many times I've been told she's dead, only to later on be told 'Ha, ha, fooled you'. Or the characters have been.
And that's as many as four-tens times. And that's terrible.

Visitor: "Is Jean here?"
Charles: "I'm, I'm sorry, haven't you heard? She's dead."
Visitor: "I'll wait."
Not everyone has had it as often as Jean, but I think what really gets her her rep is the one big one. The death of Phoenix on the Moon was a huge thing, people were sending flowers to Marvel and everything.
Then she got better.

I figured I'd humor myself and google ""how many times has Jean Grey died?"... I guess it depends on how "technical" you want to be... LOL
