As noted in the default test, this site is by ZSA, a keyboard company. Their boards are pricey, but excellent. I have both their Moonlander, which sits on my desk at home, and their Voyager, which I went with quieter key switches (brown rather than blue) for taking on the go. Their boards are very comfortable; I highly recommend considering split, columnar keyboards like what they offer if you spend most of your day at a computer.
As a side, I switched to Dvorak when I first bought my Moonlander about 6 years ago. I have only used split keyboards with Dvorak, and I have only used traditional staggered keyboards with QWERTY. My muscle memory is well isolated between the two, and I have no trouble switching between them (though as it has now been many years since I regularly used a physical QWERTY keyboard, my WPM on one is definitely lower than it used to be).
