I have all three. To me, Yuxin and CB > Aosu > Mini Aosu. And between the Yuxin and CB, the CB wins for me. Lighter, faster and the middle layers don't feel tighter than the outer layers (unlike my Yuxin).
They're both great though and I would recommend either to anyone.
I only have yuxin and rubiks for 4x4, pretty obvious what my main is. Wondering what weisu soft springs do to the yuxin, and are there other spring mods people tend to do.
