I'm using Air58 with GT-5000 grip tape and it's perfect. Buttons, shape, everything. But I still bought GPW for 159 €. Comparing these two Air58 pretty much destroys GPW. Shape is better, lighter, buttons wayyyyyyy better. RJN saying GPW is #1 mouse is near delusional tbh. Main buttons are below average and they are the most important thing on a mouse after shape.
