The common opinion is that for serious speedcubers the Dayan 5 ZhanChi is the best Rubik's Cube ever made and I think Mats Valk & Feliks Zemdegs world records kind of proves that.
For me though it doesn't suit my old fashioned style of cubing. I don't like super loose cubes and the ZhanChi isn't great with high tensioning. My original unadjusted, unlubed Rubik's Cubes are far better. They move smoother, don't catch so much and cut corners as well or better. The only downside is that they pop quite easily.
I will repeat that I am talking about my personal preference for a stiffer puzzle and speedcubers should not be put off by this video.
