Ask HN: What keyboard do you use?

As a software engineer I've been thinking about the importance of investing in the right tools for the job, specifically keyboards.

I've been looking at the Pok3r keyboard (https://www.amazon.co.uk/Mechanical-Keyboard-Cherry-Mx-Brown-backlit/dp/B01LZFFI9R/), and also looked at GH60 (https://dionmunk.com/posts/2017/05/10/gh60-satan.html) and XD60 (https://mechanicalkeyboardinfo.com/xd60/) -type keyboards. (Yeah, they're all kinda similar). I like the look of the smaller form factor, but not sure how practical it would be IRL.

So: What keyboard do you use? Why? Did you build or customise it? What's the best thing about it?

Finally, here's the project that made me think about this in the first place: Mitosis (http://imgur.com/a/mwTFj)
