Yep. THere's also how picky you want to be with the layout. For instance, I really would prefer a lower pinky-finger column than was provided on the Voyager and many other keyboards, whereas something like the Kyria is much more likely to be comfortable for me on that front.
The web-based Oryx configuration tool from ZSA is also pretty nice. As much “fun”/fun it was to learn ZMK and the process to update my Corne config, Oryx makes it very simple. Click, click, compile, flash…..and get on with your business.
