Depends which age/tech.

Every additional 'Level' in the flash decreases the overall life cycle. Mind you, oftentimes drive controllers are fancier, often doing things like treating one of the sections as a less dense flash type to improve write cycles, and keep/move longer held data into the regions treated as QLC.

But, that means that some heavy write patters will indeed wind up worse on a modern drive than the better MLC/TLC models.

Its the other way around. Early SSDs had huge P/E numbers in tens of thousands (SLC). Now we are down in the low hundreds.
