andrew.bThe Moyu brand in 2015 is analogous in popularity to the Dayan in 2010. They are arguably the best cube brand out right now. Moyu cubes are very well known to be excellent cubes for it's superb corner cutting, smooth turning, and resistance to lockups. Several world class cubers use Moyu brand cubes, including Kevin Hays, the current world record holder for 6x6, who used this exact cube in the drop (non-stickerless version).
The Moyu 7x7 is also somewhat a popular choice as well, however most world class speedsolvers use the ShengShou Mini 7x7 still.
Personally, I use the Moyu WeiLong 3x3 as my main cube, as well as both Moyu WeiSu and AoSu 4x4. Very top notch cubes.
