The REAL Problem with Blue /
Brownswitches is that the activation point is
lower than the release point.
-> You
have go travel a certain distance up after a keypress to be able to press again.
Tactile feedback probably is just some kind of preference.
In Theory black / red switches are better suited because the release point and activation point are on the
same heigth which is a side effect of them requiring a linear force to be pressed. (no tactile feedback)
Aaaaaaand, even though in theory red/black switches got an advantage it probably is extremely small. I mean... Cookiezi uses a blackwidow (hence blue switches) and obviously can stream just fine.
I'd recommend going for brown / blue if you want tactile feedback (brown requires less force than blue) and red / black if you don't want.
