1992 or 2005 in my opinion beats both 2002 and 2017 right now imo. 1992 had Flair, Savage, Hogan, Bret Hart, Taker, Warrior, Razor Ramon, Mr Perfect, DiBiase, HBK, Kerry Von Erich, Yokozuna, The Road Warriors, Nasty Boys, Roddy Piper, Owen Hart, Jim Neidhart, Big Boss Man, Davey Boy Smith, Jake Roberts, IRS (Mike Rotunda), Snuka, Slaughter, Sid, Tito Santana, Rick Martel and Kamala.
And 2005 had people like Cena, Edge, Batista and Orton rising up. Awesome wrestlers like Eddie, Angle, Benoit, Jericho, RVD, Booker, Undertaker... Heel Triple H. And then you had other guys like Kennedy, Lashley and Benjamin all making a name for themselves. Shawn Michaels was awesome during the Hogan storyline too(i loved the summerslam, personally). And then you had Finlay and JBL who were epic heels. And London & Kendrick.
