Apple Magic 1st Generation model A1843 black. I've used IBM Model M's, Sun Type 3, Sun Type 5, DEC LK201, DEC LK401, the horrible HP 700-series stepped keycap things, NeXT non-ADB, many generations of Apple mechanicals, Honeywells, Cherrys, Das Keyboard, and a bunch of random $5 rubber dome rubbish. I've come to like the minimal travel, soft but audible noise, and break in the resistance partway down the stroke. And a Logitech MX Master 2S mouse.
