Just because a cube is popular does not make it good, please contact me or do your own research for recommendations on what cube is best for you, this video is for interest. The most popular 3x3x3 is by far the RS3M 2020, no other cube comes even remotely close. Second place goes to the QiYi MS 3x3x3, third to the QiYi Warrior S, fourth to the Gan 11 M Pro, fifth to the Gan 356m, still really popular despite being old and not as good as the Gan 11 M. Data based on last 90 days sales as of uploading the video, abnormally sized and shaped cubes are not included.
