I'm using Kailh Red right now, so pretty much MX Red, but to me they are weird for gaming. The Keys are so sensitive that i sometimes press A or D when trying to just run forward just because my fingers are hovering over them. Also, the travel distance is quite long so repeatedly pressine a button, like Melee in MMORPG (or, in my case, Warframe) is a pain for me. I would either get O-rings to shorten the travel distance or get tactile Switches instead, but in the end its up to peoples preferences.
