to add/modify a bit of what ghadilli said
ghadilliThe reason is that up until recently, the options were Cherry switches (bad) or cheap Chinese clones (worse). Since the patent expired, Cherry switches have been superseded by basically any other switch maker that cares to make one. The only reason to buy Cherry switches these days is blind brand loyalty, as the only switches they outperform are the absolute cheapest of the cheap Chinese clones.
this is mostly true, but the exception would probably be retooled cherry mx blacks or hyperglides, which are solid budget-mid tier offerings when lubed although a bit scratchy if not
but yeah definitely don't look to cherry for a satisfying tactile or clicky switch unless you like BARELY tactile switches (and even then there are less scratchy options)
ghadilliIn general I always recommend people avoid tactile switches unless you work in a cramped office with people on top of you, because there is no way to make a tactile switch that feels even half as good as a halfway decent (i.e. not Cherry) clicky switch, but to each his own.
while it may be true that the tactility of mx-style switches is not as good as like an alps or topre on average, I do think there are some mx tactiles that can fill the niche if need be (but they can also get very expensive since so many of them are either frankenswitches or zeal). for slightly more affordable and really solid mx tactiles, I would recommend boba u4ts if you can find them.
ghadilliThey're far smoother than any linear, Cherry-derived switch I've used, including stuff like the NovelKeys Creams which claim to be self-lubricating.
not only is that 'self-lubricating' idea with POM a total lie, creams are ironically considered one of the scratchiest switches on the market unless they're HEAVILY broken in. it's true that mx switches basically require lubing to reach their full potential unlike a lot of other designs, but I do think most jwk switches tend to be very smooth overall.
ghadilliThere are also a lot of other 'premium' keyboard makers that are coming out with optoelectric/Hall-effect keyboards that are far smoother than anything you can achieve with a contact-based switch. And finally, the best tactile switches you can get pretty much anywhere are going to be Topre switches, as they're a fundamentally different design from Cherry's (Dome-over-coil vs Plunger-in-box) that work much much better for silent, tactile applications.
I definitely agree that it's hard to beat a good HHKB for office work due to the quiet tactility and portability, but unfortunately topre and hall-effect switches are still not commonly an option in the high-end custom world. you can find fancy keyboards that support alps-compatible pcbs, but a) well-maintained alps are still hard to find and b) I find they still sound best in their original plastic chassis most of the time
