Wait you mean the GeForce Experience overlay? I must have reassigned that right after installation so I didn't remember. But at least this one warrants having a hotkey in the first place!
I've reassigned it to Ctrl+Shift+Alt+] because that is one of the key combinations I'll never press accidentally... or intentionally, for what it matters: what do I need this overaly for anyway? Also, it's also somehow easily memorizable, after all, I still remember it after 4 years since I've bought my NVidia graphics card.
While I agree that the specific hotkey used for the overlay is unfortunate,

The overlay allows you to access a number of functions in games, much like the Xbox overlay. You can turn it off entirely if you don't need it, but otherwise the global hotkey is an integral part of it, because it's the only way to invoke it.
Contrast that with Catalyst Control Center which was a regular windowed application that you usually opened when performing first-time setup and then never needed to fiddle with those settings again. And it had a global hotkey AND a context menu shell extension, which took a couple seconds to load every time you right-clicked the desktop. It was insane. Loosely quoting Raymond Chen - noone ever got promoted for _stopping_ a feature from shipping.
