If I wanted to buy this for my brother, for christmas, would I be able to? And which switch would I go with for gaming, without being able to ask him personally or have him try some out? Is brown my best bet?
I would say if it is his first mech and he likes the way his current keyboard is feeling while typing (I believe he's using a rubberdome keyboard), I would suggest brown switches. I guess the linear switches (MX Red/Black) are maybe too much to adapt to, especially if he is using it for typing/surfing as well. When I recieved a keyboard with MX Black they were to heavy for me and my fingers got tired real fast and I missed the actuation point, the force you need to overcome so that the key press is processed.
I never tried MX Reds, so I don't know how they feel or if they would've changed my mind if I hadn't got a MX Black keyboard first.
You can try luring the answers out of him and ask some light questions that won't reference to the Ducky keyboard. Like if you were searching for you and you would like his input on the topic or stuff like that.
