Cartridges or optical discs?

Good luck repairing an optical disk that is suffering from oxidization of the data layer, which was extremely common in the PS1 days.
The optical disk laser also degrades over time, many of the early disk-based systems are suffering from that very issue... Yet a SNES will still run like the day it was made.

I never had PS1 games with that problem, so I'm not sure if it can be called extremely common.
