I have a Gan standard skewb, a Gan enhanced skewb, a wingy v1, a rs maglev skewb and a cyclone boys magnetic skewb. I would say the gan enhanced is the best but not by far, as the Gan standard and the wingy v1 are very good too. I currently main the gan enhanced and the wingy is my backup. I think I can perform almost as well on the standard and the enhanced, but I have higher chance of getting +2s on the standard version. I think the cyclone boys magnetic skewb is also very good too, but the corner cutting is not the best which causes some lockups in solves, and I’m 0.5s slower on the cyclone boys magnetic skewb than on the gan enhanced. The rs maglev skewb is the worst imo even though it can corner cut a bit better than the cyclone boys magnetic skewb. It feels papery and not very enjoyable to do solves on. I have cube drops in almost every solves, and it is the worst skewb I’ve ever tried, even worse than a qicheng skewb with ball bearings. All in all, if you are getting tons of +2s on the standard, just get the enhanced. However, if you are able to control your Gan standard skewb by adding a few drops of thick lubes, it is just as good as the gan enhanced but faster. Hope this helps!
