Common complaint about Cherry MX switches? Too light.
Common complaint about IBM Model M and Alps? Too stiff.
Preference is preference, but there are clear trends in way these keyboards are perceived. The amount of effort invested in ergo clears should tell you something about the problems Cherry have in trying to get a good tactile switch (within the limitations of the MX platform, which is part of the problem — the ideal feel may not be attainable with their one-shape-fits-all ramp design). Clears are probably on the top end of the balance range—I would say that overall preference appears to be towards something a bit lighter—but they are by no means stiff: give something like a Model M or Matias Tactile Pro 3 a go sometime. Or an Acer! Compared to pretty much everything else out there, Cherry MX brown and blue keyboards are light!
Think of it this way. You start work at a new company. This company isn't going to have an à la carte trolley of keyboards where you can choose anything you want, any switch, any weight. Chances are you'll get some dire rubber dome. But imagine the company wants everyone to have something usable (I did read of a company that bought all their staff Topres!!) — what would you choose as your stock product for a whole office? I think Matias actually found something that sits nicely between the extremes, and so far it seems to be a well-received switch. It just needs a bit of lube — that might be to do with the strange one-arm actuator leaf inherited from the Alps/Forward SKBM design (I don't actually who designed Alps simplified! I have a 1991 spec sheet with Forward's name on it, so it may be that Alps had nothing whatsoever to do with the design, simply allowing their manufacturing partner Forward to make them with the Alps logo on.)
Dell introduced a nice keyboard a few years back, the KB1421 (no idea who the OEM is) — smooth and tactile rubber dome, like Topre but with a sharper feel. Sadly it's still fairly loose and rattly. My biggest concern with those isn't the switches, is that all the bleeding letters come off the keys : P (Not for most people, but in worst cases, you can ruin the pad printing in a few months.) That and the keycaps are probably ABS, so you don't get very long before it looks horrible.
