Keyboards I like:

Keychron V6 - https://www.keychron.com/products/keychron-v6-qmk-custom-mechanical-keyboard

Keychron makes awesome keyboards, which double as shields and maybe a club if you need it. They’re heavy! I love the Keychron V6, specifically, it’s a full sized with a dedicated numpad and of course under-key RGB - because that’s mandated by law now, right? The key feel is very comfortable with the Keychron K Pro Brown switches which are great for typing on. It’s not overly loud (there is an “acoustic pad” under the PCB to mute the sound), but comfortable return and feeling.

The V6 includes 4 programmable macro keys (Circle, Triangle, Square, X) and optionally a clickable knob for volume/mute that is reprogrammable. A friend reprogrammed the knob for zoom in/out and click-to-100% - a great idea!

Programming is via the open source QMK app, which is super easy to use: just launch the website in Chrome/Edge/Opera with the keyboard connected by USB and edit/remap the keys, create macros, etc.. Super easy and no proprietary software.
