I type about just as fast on my flat key laptop keyboard as I do on my mech keyboard. I honestly like them both equally, but for different reasons.
My mech keyboard just feels damn good when I'm typing, it's a satisfying experience. Also, I am more accurate with it because of the way the keys have more travel.
IDK, favorite keyboards is an extremely subjective thing. I'm a huge fan of mine (which is the same as yours, only with mx blues, so it's more clicky). I think everyone should give them a try, simply because the build quality is better than basically everything in your local best buy.
