I haven’t tried both. Nor am I a keyboard hardware enthusiast. I have just spent some time modifying my keyboard through software (Linux X Server).

I don’t get the apparent fascination that (mech) keyboard enthusiasts have with small keyboards. I can understand moving or removing the keypad since it displaces the mouse (then again, “don’t use the mouse!”), but beyond that I don’t see the appeal except for the aesthetics.

I think the happy hacking keyboard has the missing keys on the FN layer. Hopefully the FN key is programmable, or else you are stuck with whatever the manufacturer wants the FN key to mean. (Pet peeve of mine: cheap keyboards now seem to come with those dang FN keys which can’t be reprogrammed like the regular keys and are just for garbage multimedia functionality.) With a regular boring full-sized keyboard I can program/re-purpose whatever the key is on the equivalent position to the FN key, or choose another key entirely. Right now I can access all F1–F36 keys by using a series of modifier keys right in reach of the glorious Home Row (prostrates). That’s just by modifying my standard keyboard in X. And of course I can access F1–F12 without using modifier keys since I have an (almost) full-sized keyboard. That way I get the best of both worlds: I can use modifier keys to access every key from near the home row, or just one-key while using a fidget spinner with the free hand.

With most mechanical keyboards I’ve encountered the FN key is fully programmable, along with every other key on the keyboard. Typically rather than having the functionality hard coded the FN key will activate a second layer, it’s similar to how shift activated a layer of uppercase characters, but with different functionality.

On mine I have a key that flips into a symbols layer, placing characters commonly used in programming either on or close to the home row, and flips hjkl into vim style cursor keys. I’ve also got another layer on a different key which disables almost all my customisations and turns it into a standard qwerty keyboard for gaming.

If you’re deep into layout customisations via X I suspect you’d really like a decent mechanical with customisable firmware, and probably a few spare keys for mapping to layer shifts.

Xkb gives me eight different layers just on the shift keys (not the control keys etc.). Just takes a ton of time to learn because Xkb is borderline arcane (:)) and because you have to do everything manually if you want something beyond “swap control and Caps Lock”.

If time is money I wouldn’t be surprised if I could have saved a lot of money by just buying a mechanical keyboard with good on-board firmware and programming. At least I have a hard time imagining that the programming would be harder than on X.
