IBM PC, PC/XT and original (84-key) PC/AT keyboards were Model F, which was
buckling spring with capacitive sensing.
IBM PC/AT enhanced (101 key) and many PS/2keyboards were Model M, which was
buckling spring with membrane (electrical contact).

Almost all non-IBM PC keyboards, even if they were expensive, were cheap
crap. Northgate was a notable exception, though they did offer some in the
"cheap crap" category also.
