I've been a huge fan of the Microsoft Sculpt for years. Its the only keyboard that doesn't hurt my wrists/hands hurt. Just my personal preference.

I tried the Moonlander for a bit, but could never get over the learning curve (it is very very steep). It's build quality is fantastic, is amazingly customizable, but the shape didn't work with my brain/muscle memory.

I went back to the Sculpt. If they ever decide to discontinue them I guess I'll need to stock up.
