I'm not trying to sell any one contact type over another. People have their preferences. By technique I just mean that similar to how you can play piano with different finger techniques (like pushing down on the pad of the finger vs tip), you can use your fingers differently on a keyboard, which may impact their long term durability. Different switches have different required levels of force, different spring configurations, etc., but it's also possible to type "harder" than necessary. The ergo setups in particular forced me to adjust my palm and wrist positions and as a result I type softer than on a standard qwerty mechanical keyboard. In my case it was to help with finger and wrist pain (which it did wonders for). Can't help you with the scan code failures there. I never had any issues with mine, sorry. In the past, on older keyboards, some keys got squishier over time, but a dusting with compressed air would fix that. Another time I spilled water inside and had to retrace the circuits with a pencil. Some keyboards have issues with chording too many keys at once. But none of those situations resemble what you describe.
