I have a Moonlander but I could never get used to it, even when remapping some keys so that tab is where my muscle memory expects it to be. But maybe trying to use it for both windows (play) and macos (work) was a problem. I should give it another go. Of course another issue may be that I'm very much a mouse-and-keyboard person instead of a keyboard wizard.
I should get an alternative to my old compact / flat apple keyboard one day though. It's been going strong for nearly a decade.
It might also be that you just don’t want or need an ortholinear layout, plenty of people don’t. If you like the split design and programmability of the Moonlander but not the layout and associated relearning curve, I can recommend the UHK as a good choice.
I have an Ergodox EZ for work, and I love it for that, but for my gaming I just use a typical keyboard, I couldn't get used to it for gaming.
