Keyboard is where the rubber meets the road. Every little bit of comfort and efficiency counts when you press keys thousands of times daily.<p>What works for you?
I currently use two keyboards; the chiclet keyboard on my Razer Blade Stealth (primary computer) and a Razer BlackWidow Tournament Edition with green Razer/Kalih switches. I previously used a Corsair K70 Rapidfire, which is a damn solid feeling keyboard and I actually prefer the Cherry MX Speed switches to the high-actuation Razer/Kalih greens when it comes to actual typing (gaming, strangely, not as much). That said, I have been actively looking at options on MechnicalKeyboards.com (no affiliation) - I prefer blue switches, which the greens are equivalent to.<p>By far though I am most comfortable with the travel and feel of the chiclet keys on my laptop, which is a strange thing to say but they have an amazing feel.
At some point in my keyboard-optimizing phase I decided that trying to find the ideal keyboard was the wrong approach. As long as it's a mechanical keyboard, I'm probably happy enough, and really from that point my optimizing was just novelty-seeking. So I kept my final two mechanical keyboards: a Razer one with blue switches, and a Corsair one with red switches. When I get the itch to get a new keyboard, I just switch from one to the other. They're both pretty good keyboards, and I figure that the variety is probably a good thing. I probably switch 2-3x per year.
This is probably an unpopular opinion but I love my Apple Magic Keyboard. The way the keys click and the built-in battery make it a winner for me. It also fits in my bag next to my MacBook Pro which makes it ideal for travelling.
