I did have a Kinesis Advantage, but I did not use it that much. Very comfortable, but personally learning to touch type on Dvorak is the big difference for me. I can't say it's better than Qwerty. But it's so hard for me to break my habit of looking at the keyboard to 'cheat'. If only there's a QMK enabled, Microsoft-sculpt like keyboard, bonus would be TKL/split, and mechanical switches.
