I'm not the best 4x4 solver, but comparing to the 4x4 I used to have, this one is a tad smaller, and overall feels smoother, as well as the layers lining up quite a bit easier thanks to the magnetic tracks. Outer layers can reverse corner cut, nearly 45 degrees and feels very nice once you are done with pairing centers and edges. Given you are accurate with turning and finger tricks, the inner tracks can feel very smooth and it brings the whole cube together to have a very premium, flagship Moyu 4x4 feel. Would recommend to anyone who likes larger puzzles, and would recommend the single/double tracks for those who are new to 4x4.
