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.
