LOL, are you saying that Reigns, Bryan, Cena has charisma like Hogan, Austin, Rock, Undertaker, Flair, Piper?
Actually, you made those comparisons. Not me.
Determining who has charisma, is relative to each person's perspective So the only way to reasonably measure it for a discussion, would be crowd response. Rock, Austin, Undertaker, Flair and Piper, would all be considered charismatic because of the massive crowd responses they would get. If no one cheered or booed for them, you wouldn't even think to put them in your post. The live audience and fanbase dictates who has charisma. Otherwise, we're just talking about each of our personal preferences...which would be a pointless discussion since no one feels the exact same about each of the wrestlers that have ever been on a WWE roster.
But I'll humor your decision to discuss who we personally believe to be charismatic. You might think that the guys you mentioned from the past received a louder response because they were better talents but aside from The Rock, I'd disagree.
If you're legitimately asking about my opinion:
- Bray is as charismatic as Undertaker.
- Punk was as charismatic as Piper
- Ambrose is as charismatic as Austin.
- Reigns is as charismatic as Nash.
- Bryan is as charismatic as Steamboat.
- Cena is as charismatic as Hogan.
* I left out The Rock since I don't believe any other
wrestler could conduct the crowd the way he can/could
However, a burgeoning portion of the fanbase are not as interested in these guys because of their persistence to disregard and oppose the direction of the writing. Most of those 80s and 90s talents didn't have to deal with that pre-Attitude Era (rise of internet popularity).
