Okay, I did the full test for you guys. The L button, Z1, and Z2 all do the same thing (in mario 64). The L and R buttons ARE analogue like the GC (with the digital click), although there's not as much range of motion as the GC controllers. Give that, you really don't have to worry about that when it comes to quickly hitting the button (you do have to click it all the way down to work). If you do, then you can still use the Z1/2 buttons, as they're fully digital (you just have to reach a little bit more for them, but not much).
