Durability of non original cherry switches

[dragonken]

In the old days, a keyboard with original Cherry switches (red, blue, brown, black, and white switches) could last for years without any issues.
After the expiry of the MX cherry switch patent, the market is flooded with so many cheap OEM switches
They look prettier, better switches feel, and better sound profile....
I built 5 boards with these new non-original Cherry MX switches, and none of these can last over 6 months without issues like key chattering or not registering keystrokes.
I built a 61-key 60% board with a set of famous tactile switches.
It started malfunctioning (missing keystrokes/chattering) after 3 months of use.
I replaced the problematic switches (re-soldering) whenever I found one, and later, I found I had to repair the broken switches every week.

I have Orion TKL and lightsaver with 62g white / red switches for over 10 years, and they still work great right now without any key issues.

I would like to know is it a common issue with non-original MX switches?
Is it switch brand specific? or switch type specific(tactile/linear)?
or lubricant specific (205g0/Tribosys 3203)?

i had a similar problem last year, when various switches started to activate twice, or miss the press every now and then. my keyboard use qmk firmware and my fix was to increase the debouncing filter.
(if you don't know what switch bounce is: https://www.allaboutcircuits.com/technical-articles/switch-bounce-how-to-deal-with-it/)

if changed the filter to 8 ms, haven't had a problem since. my oldest switches have around 1 to 1.5 years of extensive use (i am a programmer).
