The IQUNIX F95 with the KAT keys is incredibly awesome. It immediately improved by typing speed from 77 to 87 wpm. Fingers glide between keys smoothly. And (crucial for me) the edges of the keycaps are not sharp, compared to so many other boards.
I paid a bit extra for the optional black paint case instead of the default silver (looks awesome seeing the black / white contrast). Haven't tried bluetooth option it has (I only need a wired version). I connect it to my Apple iMac, and it's a dream. Takes a little getting used to the 96 layout (like any 96 layout keyboard by any company).
Their customer/technical support people are very courteous. Thumbs-up all-around.
Always ask for MAC key caps at time of ordering the keyboard or you will have to pay additional shipping fee later.
Bought some side plates to match the space grey apple accessories!
