Do you have a preference on the Moonlander vs Ergodox?
I momentarily considered the Moonlander as a replacement until realizing that both the Ergodox EZ and the Moonlander are made and sold by ZSA.
I have an ErgoDox EZ as my daily driver, and have occasionally had some debounce / chatter problems, but they've never been that serious for me. I bottom out hard on every keystroke, which is not ideal but I've never been able to retrain myself away from it, and I think that's part of why I have the issue.
Bumping the debounce up a bit worked for me. YMMV.
I've also had no debounce issues across two of them.
