I've had an Ez for years and I'm typing this on my brand new Moonlander. I think it's nice, but I don't think it's that much of an upgrade over the Ez. The new thumb cluster is a bit better than the EZ IMO, but it's not a complete win because of the hinge that creates a pretty wide gap between the main board and the thumb cluster.
I don't regret my purchase but if I were you I'd wait for something a bit more consequential, maybe a Moonlander Mk2. Or a more drastically different keyboard, like a manuform or a kyria for instance.
I was going to buy an EZ myself but went with the Moonlander because of the smaller size as it felt counter productive to have a split keyboard for ergonomics but have my hands hurt because they keep stretching to reach the thumb cluster.
I just learned about this last night, and was really considering it. One thing that I wasn't sure about is the size-- I already love the ergodox I've been using for the last 6 years, and reddit says the moonlander is much smaller feeling.
Huh, smaller could be better. I have huge hands but do not utlize a lot of keys on the Ez: I basically use home row and the big buttons in the thumb cluster ...
If you have smaller hands, consider a Kyria. I use an Ergodox EZ and while I'm generally happy with it, it's quite difficult for my thumbs to reach all but the first key in the thumb cluster.
