I would rate Chris Jericho at the same level as HHH and that says more about Hunter than Jericho.
HHH was pushed relentlessly, in and out of DX, with and without Chyna, and before and after he got with Stephanie.
If you look at how much HHH has been pushed he should be as big an icon as Ric Flair, but he's not.
I was at the Raw show in Tampa in Dec 99, where Stephanie turned heel to start the McMahon-Helmsley era and I remember even then that didn't really get HHH over.
For HHH to get over, it took him beating Cactus Jack in at No Way Out 2000 with a retirement stip.
Hell in a Cell still meant a lot at that point and Mick Foley picked the match so for HHH to destroy and "retire" him clean it meant a lot.
After that he inexplicably became the first heel to retain the world title at Mania 2000 and stayed in the main event scene for the next 10 years or so.
Chris Jericho never ever got close to the same pushes in WWE even though he was over from the day he debuted in '99.
In my view, HHH never moved the needle in ratings after he came back from an injury in 2002.
His career is littered with examples of him "needing" to win because he wasn't good enough to stay relevant if he lost.
