I decided to get a skypad. I have only played on slower mousepads, so I was unsure how I would transition to a fast mousepad.
My main reason at first for trying a skypad/glass mousepad was because I was frustrated with cloth mousepads slowing down overtime, and also annoyed with the process of trying to clean cloth mousepads.
Since switching to the skypad I realized I really like it. People always say glass is tougher cause its faster and more difficult to control the mouse, expecially with stopping. But after a few days of adjustment I realized that the lower friction surface means less movement can move the mouse, but the mouse moves slightly more consistently with slight/light adjustments such as finger adjustments. A similar analogy might be pushing a very heavy weight on a rough carpet, you probably have to hit the weight harder and harder and all of a sudden it will just jerk foward inconsistently. While trying to push the same weight on ice, just a slight push and the weight will move foward more consistently with the force applied. Because of these reasons if you have a fingertip dominated grip I recommend you consider trying a skypad/glass mousepad.
Also with glass, It feels more raw, just me and the mouse no safety net. People say you need a mouse sleeve but you really don't, I never wore that.
Lastly, a faster mousepad like the Skypad may facilitate accelerated improvement because it provides higher input-output fidelity. With less friction, the mouse movement more accurately reflects the user’s motor intention, resulting in cleaner error feedback which probably leads to faster learning.
Edit (additional thing i though of): with faster mousepads you need less force to overcome friction so your arm does not get as tired as fast, which means you can play for longer sessions at peak performance. So id say this is another reason I have a preference to faster/low friction pads such as the skypad.
