I have a Unicomp (actually two, but one is the quirky rubber dome they made) from the early 2000s and a Scotland-made one from the 90s, and they feel pretty similar. I understand the biggest thing is just that molds wear out over time and eventually there was a little slop. I have heard, but can’t personally confirm, that the “New Model M” they sell has tightened things back up via new molds.
