When upgrading from a Microsoft Natural Ergonomic 4000 I was debating between the Kinesis Advantage 2 and the Ergodox EZ. The Ergo 4000 was my first ergonomic keyboard (and amazing for the cost) but I grew frustrated by the layout and rubber domes. One of the blokes at work had an Ergodox and he was kind enough to give me a go. It was great fun - from memory the thumb clusters were closer than the Kinesis which would be great if you have smaller hands (for those who haven't tried the Kinesis Advantage - the thumb clusters are a little far away, using the 2 smallest keys closest to the bottom-centre isn't comfortable for me) I thought the standout feature was mouse control at the hardware level - think hjkl but moving the mouse instead of your cursor. I have yet to find a way to do that with the Kinesis in software - if somebody can do this please let me know! The reason I chose the Kinesis is the key wells felt great. It felt more natural for the keys to be the same distance from my fingers as they moved forwards and back in an arc. The Ergodox was a lot more portable, though I thought I would be frustrated having to set up each half at the perfect distance and tenting each time. You also have a greater switch selection than the Kinesis Advantage if you want something clicky.
