Flash memory certainly does "fade" and separately has a maximum number of writes (reads are no problem). See "wear levelling".
I know two people with really old pre-touch Kindles, both fine.
A Kindle Touch June 2013, Kindle DXG Oct 2013 and an old PRS350 all have good screens too.
I've seen a Storybook Cover & Kobo H2O with cracked screens. Unlike LCD, the screens are a high proportion of price and also there may be "calibration", so I'd not replace a broken eInk panel unless replacement was < $15.

I've never heard of eInk "fading".
LCD (two reasons) and OLED certainly do fade. Eventually, colour usually shifts first, though I have some 18+ yo LCD that are OK. LCD and OLED do also suffer "burn in" (dye fade on LCD and phosphor ageing on OLED), though not as much as CRTs.

Edit: I may use my original Kobo H2O over 30 hrs a week sometimes.
