I like that the thumb cluster on the Moonlander has an adjustable angle - the fixed angle on the Ergodox EZ wasn't the most comfortable fit for me. As well, if you are going to be carrying the keyboard around with you, the Moonlander folds down flat and comes stock with a neoprene carrying case and the hex wrench to readjust it, so it's fairly trivial.

I've also had no debounce issues across two of them.
