Honestly, the inner layers are better on the AoSu, but I like the magnet strength on the MGC and its not crazy fast (then again I could set it up, but I don't feel like buying a $40 when I like mine that I already have)
Good deal I have the MGC 4×4 and I like it as well as the Xman Ambition you wont be disappointed.
tho I prefer the Moyu GTS2M but hey its like $45 so... you do the math haha grab that cube and dont look back!
