No it was better because the overall talent was still better then TNA during Christians title runs. You want to know who else was winning and having legitimate reigns with the NWA title around the time Christian had it? Rhino, Raven, and Abyss. Man he really had some great company there
You also left out Sting, Joe, Styles, Angle and Jarrett. I think that's overall better talent then Scott Steiner(who Christian also faced and beat while he was in TNA) who Booker T faced in a "straight jacket steel cage match" at superbrawl 2000, well gee i wonder why no promotion does that gimmick match anymore.

Fact is out of the 4 WCW titles he won in WCW 3 of them were against either Jeff Jarrett or Scott Steiner who Christian also had feuds with in TNA. Christian had much better competition in TNA with all the guys i mentioned above while Booker T had Luger, Nash, Steiner and Jarrett.
You mean the time slot that had it going head to head with RAW? Put TNA head to head with RAW now or back in 2006-2007 and see how much it gets dominated and how much lower its ratings get.
Like i said ratings don't necesairily mean top quality. Ring of honor has had 4 5 star rated matches in it's time with a tiny fanbase while WCW during Booker's title reigns had tons of swerves, stupid gimmick matches, a man as womens champion and quick title changes with a die hard fanbase who had been there during it's best years. But of course because the ratings were better that means WCW must be better right?
Vince Russo booked the Attitude era in WWE as well. Does that mean that we should discredit every title reign from that era?
Not at all. In WWF Russo had McMahon to filter all his shit ideas. Vince always had the final say on what happened. On WCW when Russo had free reign he made a mess of things and that's me putting it nicely.
I also remember Triple H losing the WWE title to Vince McMahon in 1999. If Booker gets credit taken away then so should every single person who was holding the WWE title around that time.
The difference is though is that the WWF had guys like Triple H, Stone Cold, The Rock etc, legit top guys to keep the title credible. On WCW Booker only got a chance after all the top guys left. His competition was much worse with Jarrett, Steiner and Nash. Hell Russo wanted to put the title on Fucking Tank Abbot of all people. Fact is Booker only won the WCW title when there was no one else to challenge for it. Your kidding yourself if you think he was going to get near it while Hogan, Sting and Goldberg were there.
This is a kayfabe tournament. Backstage things and contract issues don't come into play. Christian was beat clean by Booker T in TNA and that's all that matters.
Triple H has lost clean to Shelton Benjamin and Jim Ross. Does that mean they would advance in the tournament ahead of him too?
Hell Undertaker has lost to Ken Kennedy and A-Train. Stone Cold has lost to William Regal. Like i said win loss records mean shit.
So what's Christians prime exactly? If it's his first couple years in TNA then Booker T's WCW main event run trumps that. If it's his recent feud with Randy Orton where he only had one DQ win and held the WWE title for a total of 30 days, then Booker T's 126 day reign as world champion in WWE trumps that. Christian loses regardless of your argument.
No he doesn't. Mainly because all of Booker T's WCW title reigns were pure garbage. Christian's run in TNA was much better. He faced Sting, Joe, Styles and Angle. Christian even faced Jarrett and Steiner who Booker won 4 of his titles against. So yes Christians run in TNA was much better and yes Christian would beat Booker T.
