TBF my "attitude era" experience is from very late 1999, had poor reception on the channel that had WWF so I always just watched WCW as a kid. Made an effort to fix the reception after Jericho switched.
I had strong opinions on pretty much the whole roster back then. Loved Jericho, Kane, The Rock, Too Cool, The Radicalz (Benoit most of all), the Hardy's and Lita, the Dudleys, Undertaker (though significantly less than Kane), Angle, Chyna.
Love-Hate Austin, never MY guy but always entertaining
Hated Edge and Christian. HHH, Big Show, T&A (all 3) and Vince
I just felt almost pretty consistently involved in matches, there weren't a lot of times where it was two guys or two teams wrestling I didn't give a **** about one way or the other.
Smackdown is just full of programs I care about, Miz/Ziggler, Rhyno+Slater, Ambrose/AJ/Cena, Wyatt, Becky, Nikki/Carmella, God I think I'm even coming round to the Hype Bros.
Raw though... It's kind of all just mildly interesting. Only Jericho feels especially entertaining to me. I'm now watching Raw on YouTube and Smackdowns full episode +Talking Smack.
