I can speak from experience with the Ergodox EZ version of the ergodox. I should have done more research before purchasing it. I've experienced a stubborn debounce problem that's been mentioned by other users in forums and QMK issues over several years. I experienced it with the original firmware, and also with QMK, which I tried out of desperation. Switch bounce effects are somehow unaffected by turning debounce up to 250ms. It's not my only ergodox, but it's the only one with this problem. I've come to the opinion that there's something structurally wrong with the EZ's design.

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've never had a problem with my Ergodox EZ. Maybe it was a particular run that was problematic? I bought mine in August 2018.

Debounce can be very personal - exactly how you push the keys has a significant impact on bouncy/chatter your keys are. It's not just about the mechanisms.

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.

There's a version and batch number on the bottom of the keyboard, mine's batch 3a and V3. From what I've gathered it's hit or miss. This EZ is the only keyboard I've had issues with. The interesting part is that it's specific keys. Iffy solder joints were my first guess but that checks out. I haven't put the effort into checking components yet.
