When I first heard the GSN Pyramid's idea with each 7-out-of-7 adding $5,000 to the next Winner's Circle, I thought it was a nice evolution. But watching day after day, it made the individual rounds feel like a series of failures during which they were keeping score. i.e. - well, you didn't add $15,000 to your Winner's Circle, but you did manage 17 points along the way. (Oh, and you won the game.)
For me, the same kind of feeling permeated the Donny Pyramid. Maybe it's knowing the old version too much. But, put side by side, the Donny version had an especially anxious energy. The classic Pyramid afforded you about 4.28 seconds to work on each answer; the 6-in-20 format only allows 3.33. As Travis alluded to, some of the problem on the Donny show could have been in what words were chosen, and especially what order they played.
An Osmond Pyramid had about 20 minutes of show in a half hour slot, while the Strahan version is right around 21:30. Based on that, there's a case to be made they literally didn't have time to play the old game in 2002. But I wonder what the end result could have been with the Donny version if they approached the runtime problem in a different way.
