Given that Jackson Ultima blades are now among the most popular figure skating blades, the video (and Broadbent's Wellness Gauge) can't be completely "right", in judging Jackson blade shapes bad, at least according to some figure skaters.
In particular, the video assume the distance the tail hangs in the air when the toe pick touches matters. It doesn't.
On Jackson blades, there is typically less distance to rock forwards to the toe pick, because the toe pick is (I think) closer to the front of the foot. However, the spin rocker profile is also more curved (shorter spin rocker radius), so the part of your foot that is closest to the ice, and the alignment of your toe, can still be good.
What changes is the amount of foot motion required to roll from the sweet spot to your toe pick. Maybe what distance you want may depend more on your experience than anything else?
As someone who switched from MK (Dance) (and earlier, Wilson Coronation Ace) to Jackson (Dance, Synchro, and Supreme), I would certainly agree it is a huge change. You have to learn to move less, and to control movement more. Whether or not that is good or bad is a matter of opinion. Not surprisingly, as with many types of sport equipment, there is a lot of disagreement.
Given a choice, I would have stayed with MK Dance, which I loved. But cost directed me otherwise (and I like gadgets - the Matrix I blades, with interchangeable relatively cheap runners, appealed to me), and I've sort of gotten used to the Jackson shape, though I hated it for a couple years.
I think that when someone says that one type of very common figure skating blade is much, much better than another type of common figure skating blade, you need to take into account what that person is used to, as well as what other influential people (e.g., coaches, skate techs) that they know say, and recognize that their statement can't always seem true to everyone. For professionals, in which category I place both blade-maker reps like the Jackson rep who made the video, and high level skaters and coaches who get free blades and/or are sponsored by the blade-makers, money would be a factor too. In this case, Paramount chose to imitate the MK and Wilson blade shapes more than the Jackson Ultima blade shapes - so it is not surprising that their video rep would dis the Jackson blade shapes.
But we've travelled far from the Samba Dance blade / heel lift question...
