The GAN 12 maglev is, in my opinion, the best 3x3 ever. It's similar to the 11 and 14, but has slight differences that still make a big difference. If you want your gan 12 to be like some pro cube solvers' 12's, you can put the settings to Tymon Kolashinski's settings when he broke the average world record, and you can put in the lubricants Nebula and Martian to replicate Tymon's Cubicle lubes. My overall experience with this cube is superb, and I really recommend adding PVC coating to it to get the best performance.
