I'm enough of a dinosaur to remember when mechanical keyboards were the only ones out there. I liked the original IBM PC keyboards, which were not mechanical but had a mechanism to make them feel a lot like a Selectric (pressure then release that IBM called a ‘bucking spring’ mechanism).

Starting a few years ago, I started experimenting with mechanical keyboards. The key to getting one that you like is matching the type of key to your typing style - and whether you have office neighbors who might have an issue with typing clatter. After quite a few keyboards and types of keys, I landed on the Kailh low-profile blue switches as the perfect ones for me. They're not nearly as noisy as full profile blues and you still get that building pressure then release before the key bottoms. It turns out that Havit makes fairly inexpensive prebuilt keyboards with Kailh low-profile blues. I prefer tenkey-less, so I got the Havit HV-KB390L, liked it well enough to buy another just to have one at the office and one at home.
