This is the finishing move that has made more or less anyone Chris Benoit has been in the ring with tap out. Chris Jericho's move today is featured as a secondary finisher that does nothing in terms of finish the match as much as the Codebreaker does.
Actually one could say the Walls of Jericho has become a signature move at best. The Crippler Crossface however is somewhat featured by Bryan Danielson now, in a variation. It is still an impacting move in the business, and unlike the Walls of Jericho, this is the move that can be more or less slapped on at ANY given time.

This video has Benoit explaining the Crippler Crossface, and it practically shows how devastating and how easy it is to smack on. Chris Jericho's Walls just cannot do the same, it doesn't have anywhere NEAR the same sort of surprise elements.
And not only that, but the Crippler Crossface looks like something that genuinely hurts. Chris Benoit put so much effort and so much power into that move that even if he was trying to kayfabe it I seriously doubt it couldn't have done at least a bit of damage. On the other hand, Chris Jericho doesn't showcase half the power behind his Walls of Jericho submission hold as Benoit did with his crossface.
So, therefore the Crippler Crossface is the right choice in this.
