This feels like a motte and bailey, you made a very bold statement in your first statement, that you knew people would think you meant Brisco was a far better pro-wrestler and now you retreat to the easily defended position you actually meant.
I think just anyone could just as easily say Brisco couldn't fill Danielson's shoes if he was put in his position in '06-'09 '13 or '24 or whatever.
They're both capable of wrestling heated matches, whether that's Brisco clips in florida, Brisco vs Piper in '82, Danielson vs Morishima or Danielson vs Swerve. But I think the emotion is more palpable in Danielson and Morishima from Final Battle 2008 than any Brisco match. Jack Brisco is a capable heel, but as great as Briscos vs Steamboat and Youngblood is, I can't look at Danielson vs Roderick Strong (a horrible babyface at this time and specifically in this match) from 2006-03-31 and not say that is a better heel performance than any I've seen from Jack Brisco.
Brisco is better in Japan than Danielson, but in Brisco's case it's what makes up the bulk of the footage from his peak and in Danielson's case its something nobody thinks about when the look at his career because it makes up less than 1% of it.
