I've been using the Das keyboard for a very long time and I still think it's the most comfortable keyboard. However, they don't have a wireless keyboard, and I always want wireless devices to make my desktop cleaner. Before that, I used a Logitech wired mechanical gaming keyboard for a while, which I also really like. I also tried the Logitech G915, but I don't like the short key travel. The keychron buttons have a different feel, I understand they use different switches, which may be better than Cherry's, but the feel isn't as good in my opinion. Long typing causes the keychron keys to tire, which was never the case with my Das or Logitech. All the keys are higher than a regular keyboard, which could be another reason for my fatigue. If that ever has wifi I'll buy it on day one. On the other hand, the Keychron connection is really good, I've never experienced a disconnect in daily use.
