It is the same signal, I'm not sure but potentially drivers, microcontrollers, and other things may impact latency though. Not that mechanical keyboard enthusiasts seem to be focused on that.
However, the type of switch you use can have an impact on all kinds of things, the speed at which you can type, the accuracy of your typing, your long term health, etc.
Certain types of switches are also better suited to specific activities. For example, linear switches can usually be pressed faster, which makes them very slightly better for gaming. There are even gaming oriented linear switches that have reduced key travel to further increase speed. The speed impact is going to be near non-noticeable in its impact on game performance for everyone but elite gamers, but anyone is going to be able to tell that certain switches fatigue their hands less than others.
