This mini-joysticks is the same used in console gamepads, the durability depends on manufacturer quality.
Look at Mouser.com and see the price of brands ones and look at eBay or Alibaba and see the prices of no-name ones.
Exist "mini-joysticks" with HALL sensor (contact less) instead potentiometer - used in some console gamepads - but since these cost ~5$ and the ones with pot' cost 0,50$ the joystick manufacturers dont use the first type.
Despite their antiquated look and outdated electronics (USB 1.0, 8 bits) CH controllers have reputation in use good
quality potentiometers, at least better than
Saitek ones.
