Yes, I find QMK easier to work with, and easier to read (As a developer).
The firmware (for each of my boards) gets more and more refined with time. My alpha keys and main function layers are all setup nicely. I occasionally adjust a key or two, mostly media keys, volume keys etc.
The only major thing is like to add is a switch for windows/Mac keycodes. MacOS is my default, so certain shortcuts don't function correctly when I use Windows, where the main shortcut enabler is the control key. I'd like to have a swich for that.
