I have Jackson Freestyle boots with Aspire blades built-in. For jumping, at our level, they are good enough. I can't spin, but that has more to do with me than the blade, I think!
The Competitor is stiffer, but stiff doesn't always mean better. Boot fit also depends on your weight. I'm petite, at <100 lbs, and the Freestyles are perfect once they're broken in.
