I have a Lily58 that I love. I put mine together myself (save for soldering. The place I found mine offered a service to do that before shipping) so it’s a bit different looking than this one shown in their preview, but it’s the same layout.

I love my Moonlander keyboard at home: https://www.zsa.io/moonlander

And I built an Iris for my desk at work: https://keeb.io/products/iris-se-kit

I use a DIY keyboard called the Dactyl Manuform and I love it to bits

There’s several out there depending on what you want. I don’t mess with anything like ortholinear or Ergodox because the stagger is weird. So in the “regular keyboard but split” space, if you don’t want to build your own, there’s the cloud9, the dygma raise 2, and even such like the Feker Alice looks cool too - it’s not mechanically split but does give the split curve feel like the MS Ergo.
