I’d only consider the Moonlander if you have large hands. I have very average male hands and the Moonlander thumb cluster was quite painful. It’s far away and the keys are angled weirdly. Other good prebuilt options, from close to a regular keyboard to ticks off all ergo features:
- Kinesis Freestyle Edge RGB
- Dygma Raise
- Keyboardio Model 100
- Kinesis Advantage
- MoErgo Glove80
My experience is that once you go ergo, you’ll end up wanting all features, so you’ll save yourself a lot of money by immediately buying a Kinesis Advantage or Glove80.
