Same here.
I was skeptical of the ergo properties of the Moonlander to begin with. I was coming from a UHK and wasn’t all that sure ortho-linear was going to be that big of a difference.
I was wrong. After about a week of getting used to the layout and retraining a couple of fingers, I was up to full speed on the Moonlander. MY absolute favorite layout items are space, backspace, and enter. I put them all on the thumb cluster. It is so much easier to correct things because my thumb just has to hit the key right under the space bar. Incredibly intuitive and fast. In general typing on the Moonlander is just comfortable.
Mouse emulation on the Moonlander is wonky though. It is had an exponential curve that makes it almost impossible to use, especially if you have several monitors. The UHK’s mouse emulation is MUCH better as it has a linear curve, which makes it very predictable to use. According to ZSA this isn’t something they can really fix as it is just a part of how QMK works.
All that said, I thought I was done with the UHK. The Moonlander is just really comfortable to work on, and the RGB backlighting makes it really easy to see in low light situations. (The UHK v1 does not have backlighting. V2 does.)
But the UHK finally got it’s additional modules which for me was a thumb cluster and trackball mouse. This put the UHK back in the limelight, because it was incredible how having a mouse right where my right thumb is, was useful.
That said, the Moonlander is still more comfortable despite the lacking functionality.
The Planck EZ is another matter. It is great as well but the biggest problem I have with it is the location of the USB C port. It should be on the side. Because it is not taking advantage of its compact size for mobile applications is not very useful. you can’t have the Planck right underneath your device because of the USB C cable jetting out.
One final thing is the method of updating and customizing the keyboards. The UHK wins hands down. It has custom software called Agent (available for Mac OS, Windows, and Linux) that can change the keys in real time. You just load up your layout and change whatever you want. When you click save, it automatically loads it to the keyboard in a matter of seconds, and your changes are life.
The ZSA method is convoluted and slightly annoying. You need to go to a website to make your changes. (requiring an account to save and retrieve) After you’ve made your changes it needs to be compiled (which the site automates) and downloaded. From here you use another program called Wally (I think). This will upload the file you download to the Moonlander or Planck. You have to put your keyboard into reset mode for the file transfer to work. On Windows Wally was temperamental with me, and would not work at all with the latest version. Only version 2.# works for me. Fortunately it isn’t that bad and you don’t make changes all that much after getting it dialed in.
I wrote a little review on the Moonlander here where I go into a bit more detail on my thoughts if you are interested:
