I simply dont buy it. The way I see it - you've got gamepads. All of them are rubber dome. You've got the speedrun scene, all of them use gamepads.
You've got the mechanical keyboard scene, which is set up to be a cost sink for no reason. (Margins of probably 500% and more.) You've got youtubers, who are sponsored by manufacturers, all of a sudden realizing, that they play Super Mario Bros. better on a mechnaical keyboard - while those youtubers usually are the ones hyping up trends for revenue reasons anyhow - and you've got the highest need for switches not 'double registering' on a control scheme thats mostly used for shooters, where movement isnt even analog.
So i call, BS, BS, and BS.
Oh - and I'm writing this on a butterfly switch keyboard on a Macbook, that was prone to 'doubleregisting' keystrokes - let me tell you -- you'd notice, if you were double registering while typing or playing -- all the time, you'd usually not - on any rubber dome keyboard. In the case of the Macbook air I'd eventually install a utility called shaky, that would prevent doublepresses, unless a few ms were in between them - because the double registering keyboard got so annoying. Even when only double registering once in a paragraph of text.
I call marketing fluff. Cherry blue switches not feeling as good as buckle spring switches in the IBM days, and an enitre artisan community - thats set up to sell you on 200USD+ keyboards for no reason.
The rest is confirmation bias. (I've bought it, so it must be good. See:
