I probably should have appended a lot of disclaimers to my post. Keyboards are an awfully individual thing. Some people like quiet keyboards, some like to hear aural feedback. Some users like chicket-style keys, others like keys like on the original IBM keyboards that mimic early electric typewriters. Some like keyboards with short key throws (e.g. recent Macbooks), some like longer key throws with some tactile feedback.
My idea of a perfect keyboard is the Apple keyboard circa the time that Apple was selling Bondi Blue and white Macs. The A1048. Shockingly, you can still get one of those keyboards, and you can get one for a very reasonable price:

And some people REALLY love the original IBM clacky-style keyboards. IBM sold the rights to make those keyboards to Lexmark, and they in turn sold the rights to Unicomp. You can still purchase a brand new one!!!
In those old buckling spring keyboards, keys are individually sprung and produce
an assuring sound when you hit the mark correctly.
