ErgoDox family. Seems like an over all good keyboard, though it looks like the thumb cluster is a bit too far to the side. Lacks F-keys which is a minus for gaming but doesn't matter for work. I'd probably go for an ErgoDox Infinity in this case since I'm a bit paranoid about latency introduced by the I2C extension used in the other models. I know several people has posted that they experience no latency but I've found that people experience this differently. Problem with Infinity is that I just missed a Massdrop so it might take too long time to wait for a new drop + delivery.
The latency reported way back in the past does not exist with recent ErgoDox models. It certainly does not exist with the EZ. As far as I remember, even back in the past, the latency was a combination of bad cable and buggy firmware. Neither of those is the case with the EZ, there has been many attempts at finding latency on the EZ, without success. Don't discard a high quality product because a few people had issues with their hand-built keyboards. The two aren't comparable. So I'd still consider the EZ, because it is a very well made, and high quality keyboard, with awesome support. It also ships assembled, and fast, and has a sweet tenting/tilting kit. I own two, they are my daily drivers for over a year now, and am loving them.
I would also suggest looking at the
Keyboardio Model 01, which is entering mass production, and should ship in Q3 (so likely sooner than an Infinity ErgoDox). Comes pre-assembled, is column staggered, split, can be tented or tilted, comes with Matias Quiet Click switches (which are a lot quieter than my Gateron Browns in the EZ). Compared to the ErgoDox, it has a better thumb cluster, and a palm key (which is incredibly good!). The firmware is pretty much on par with QMK & KLL that power the EZ and the Infinity Ergodox respectively. The tooling around it is a bit behind (ie, no web-based layout editor yet), but that is being addressed, and by the time the keyboard ships, tooling should be in a much better shape too.
I have a Model01 prototype, and once the final product ships, that will replace my EZ at home as my daily driver (work will remain on the EZ for the foreseeable future).
