Jungkook follows the original choreography, while Usher brings his unique vibe to the performance. There's no right or wrong, and there's no need for comparison—they both shine and are equally the best in their own ways!
Usher drew inspiration from Michael Jackson, and the song carries a distinctive MJ vibe. Having Usher contribute to it is a positive choice, considering his connection to MJ's influence.
