Oils do not wreck an engine.So you will not get the answer you seek.
Some just protect better than other
It is not like throwing a rod.
Wear happens slowly over time.
Wear is also dependent upon a massive amount of variables that can not be controlled for.
Dust, local weather conditions, humidity of the very air the engine consumes, slope of the yard, type of grass, average mow time, etc, etc, etc, etc
As previously mentioned you would need to keep very accurate records of the type ( and cost ) that only the military and avaition industries can afford to do to get any meaningful answers.
Even then you need science & engineering knowledge to be able to interperate those answers .
I have only been running the repair shop for 5 ( nearly 6) years and I am yet to see an engine that grenaded because of the oil or filter used.
Even today, Briggs sell their engines with no oil filter fitted, with oil filter but no circulation pump , oil filter and circulation pump.
AFAIK B & S are the only company that sells an unfiltered engine.
However they all sell engines with different levels of oil circulation, splash lube, pressure fed big end only or full pressure lubrication.
These are not long term engines.
They are all built down to a price for an acceptiable service life ( gets shorter every season )
