You're crazy if you think Triple H is more well known than John Cena. Triple H has never broken into mainstream culture the way The Rock, Hogan, and Austin have, and neither has Bret, Sting, or Savage. I can tell you that I have brought up both John Cena and Randy Savage to non-wrestling fans, and they know who Cena is immediately, but have never heard of Randy Savage. Sting has never been nearly as well known as Cena due to him being out of the public's eye since the demise of WCW. Bret Hart is popular in Canada, but he has never seen nearly that much popularity anywhere else in the world. Undertaker is the only guy I would MAYBE put above Cena, and that's mostly because he's been around forever. Other than him, Cena is a much bigger star than any of those others you mentioned.
Triple H is well known across the world far more than John Cena. If I was to ask anyone about wrestling and asked them to name 5 wrestlers from WWF/E, Triple H would be on the list more often than Cena. Triple H is (along with Taker, who practically everyone knows) one of the last remnants of the Attitude Era, and was the top star on RAW when a large part of the audience stopped watching. Savage is the same except for more Old School fans. They were never top of the company but they are two of the best known names in wrestling. Like I said about Bret, this guy is known far better than Cena. To most Canadians, he's the best wrestler to emerge from Canada. And again, I bring up the Simpsons. You have to achieve a certain level of fame to appear on the Simpsons, and Bret Hart remains the only wrestler to ever do so.
