This. As a dancer myself, I would agree---they're not the world's best, but there are also so many different genre's of the best that it's hard to keep up. I personally don't believe the hype of Dance Moms because I know about the fake competitions, the judging, and how staged it is, but that being said, both are still fairly talented and thanks to this reality show will likely find commercial success.
Unlike cheerleading, dance has a world that never seems to stop with more avenues then can be imagines. Cheerleading doesn't have that same reach---so yes, Gabi Butler may be one of the best in the world, however, star power wise I'd put my money on a Maddie and Chloe long-term for the simple fact that dance gives more overall opportunities than cheer.
