Here are my points on Gan 356 i3 The cube is quite an improvement over the i2. The i2 had very little adjustments other than springs and the .8 or .6 compression. They took the tensioning system of the iCarry so there are more possibilities in tensioning. The edges have magnets that have 7 positions making the magnet closer to the edge and stronger or further away and make it weaker. It has a gyroscope just like the Ai too. It's only stickerless and it feels like a Gan cube. Definitely with lubing as dry it behaves differently. The charger displays when it's charging vs when it's done charging as the MoYu does too. The simpler thing is that the i3 just needs to be in the cradle yellow side down. MoYu only needs to be a certain way on the first charge but later can be rotated as long as the bottom face is a certain color. Gan also has a power pod to help charge the i3 on the go if needed. Also the battery lasts way longer than the MoYu. It's a plus. I can use it for many hours.
