ALPS themselves had so many variations over the years, then when you add the aftermarket versions to it, it becomes tricky. I never cared for the Real vs. Fake because some "fakes" are better than some "reals" and vice-versa. And Montereys are fantastic (which some call Fake alps) There are so many different combinations of leafs, sliders, housings, mountings, etc. - then you apply different springs to them and that changes each one's response. Try different caps and in different boards and the range of ALPS can go from crap to incredible. I've experienced a similar range in Cherry Blue switches, some click, some thud, some are barely tactile. Interestingly, I don't feel that much difference in Browns but I do feel it in blues. My Dolch cherry blue board (early 90's) and West German Cherry (late 80's) are lighter than my new G80-3000LSRC-2
I have an Ortek with ALPS that would make anyone fall to their knees in gratitude they got to experience such a fantastic feeling of oneness with mechanical wonder. I don't even want to take the switches apart but I will at some point and will post photos. I had a pink ALPS board that to me wasn't anything special but to some it's like Beluga Caviar. I love my Northgate, SIIG minitouch, Ortek and a few Apple boards, I don't care as much for the AT101W in comparison, though it is a very well made keyboard and is only cheap IMO because there is a very large supply of them out there. I just don't like the echo chamber it has and it's switches are ho hum, just ok with rattly caps. But I've also experienced a wide range of feel in just AT101W's alone.
