A black switch has a stronger spring, so it will be a faster switch than a red in terms of total travel time during a bottom out and release. Amusing to think of this making a difference in a game, though.
I just tested out my MX Blue kb vs. my rubber dome and yea it does make a difference.
It is almost impossible to replicate the same movement as the rubber dome with the Blues. You almost always end up moving twice the distance with the Blues than with the rubber dome.
If you play a game competitively, like Counter Strike for example, then you'll understand why this is a problem and that precision in movement is crucial.
Ex. with the rubber dome I am able to peek around corners quickly by tapping the key and strafing a short distance.
But with the Blues when I do the same "tap", I end up strafing a longer distance (basically double like I mentioned before)
This is the difference between only exposing my shoulder vs. exposing half my body including my head.. which obviously leads to higher risk of getting shot/killed especially if there is a sniper watching that corner.
This could only be avoided (and I was only able to replicate the same movement as rubberdome) when/if I don't bottom out and press the key until I hear the actuation click and let go right away... being careful not to push the key any further.. but nobody plays like that realistically.
But I understand that for some (most) people, they just play video games casually and so this is a non-issue for them. Thanks to the OP for bringing this up, I never realized it to be a problem until now and trying it for myself.
