Are its keys sticky? Or are they smooth? Because I've got little against a decent rubber dome keyboard.
The keys are quite firm with little wobble, and spring back up fast and smooth, partially owing to the "keying" of the keycap stem, and some sort of light grease coating. The keys themselves are slightly concave in the middle from all four sides, and have a rather soft feel to them that is not at all unpleasant. Actuation around 60-65g as per nickel stacking.
There's a somewhat related review
here. For some reason I recall reading a review of my exact board somewhere on the forums as well, but I can't find it anymore.
