So I got both G403... wired and wireless. Wireless is great because it has no cable. The Wired is great because it is lightweight. However, the wireless is heavier and the wired has cable drag. I really dunno which one I wanna keep and which one I wanna return. Both are amazing in their own rights. The shape is very good too.
M3 button is a bit stiff and louder on the wireless than wired for me. Quite a noticeable difference. Other than that its perfect or nearly perfect. No rattle at all too.
Quite happy, I just dont know which one to choose.
