I have switched from an ErgoDox EZ to a Model01, and while I love them both dearly, I found the Model01 to be far superior as far as ergonomics go. The palm keys are beyond amazing, they remove a lot of load from your fingers. The thumb cluster on the ErgoDox has always been sub-par (I can reasonably hit at most 3 keys there without being uncomfortable), the thumb arc of the Model01 is much easier to reach (I can easily hit all four keys, all of them more comfortably than on the ErgoDox). The custom sculpted keycaps are also something I found to make my fingers happy.
And the best thing? Camera mounts. The tenting story of the Model01 is simply unparallelled. With the EZ, you can tent to about 20 degrees or so, I think? My Model01 is at around 45. I can mount it under my standing desk, to have ideal keyboard<->monitor distance, for example. It also looks good, and with translucent keycaps, the per-key RGB really does shine.
The Model01 does have less keys, and less switch options, though. So if you want something else than Matias Quiet Clicks, or need more than 64 keys and layers aren't sufficient, then the ErgoDox is a better option. Otherwise, in my book, the Model01 wins.
