GAN15 New Black is a top notch cube! Out of the box, I have to say the Maglev factory settings feel better, smooth, quiet and very light. New Black out of the box feels looser, louder and very clacky. However, I am finding the New Black responding more noticeably to tweaking the settings, and once you have it setup, it is quite a bit snappier and more responsive than the Maglev. The action reminds me of the Gan356 maglev, which was my favorite GAN before the 15 came along. The black internals look great and it is SO light! Between the two, my personal favorite is still the Maglev. It has something dreamy going on between the ultra light weight, quiet sound and buttery smooth turning that gives it a kind of a soft foamy feel, like you're walking on a cloud. New Black has the same light weight and fast turning, but it feels more tactile and direct with a sharper plastic feel and snappier sound. Both great cubes, with that top quality GAN manufacturing quality and vivid UV coating, you can't go wrong!
