Of all of the keyboards that I have used, the ones that I found most agreeable to type on were the Apple Extended Keyboard II on the Macintoshes in university back in the 1990s.
They had a lovely spring to them. They use, acc. to Wikipedia [1], mechanical switches from ALPS.
I was thinking about getting one, along with an ADB-USB converter, but they are almost 30 years' old now and with many decades dirt under the keys, they will need cleaning.
