Maybe what my friend slck_bit meant to say (perhaps but no guarantee preempting Pop's deep end dive of typical righteous indignation) is, 'generally speaking' cartridge filters are still more expensive than the spin-on/canister type filters. Further, for what they are 'relatively speaking', the element alone, there's no reason that should be the case. However,economies of scale dictate the price. There are simply many more vehicles and more applications using spin on type than cartridge filters.
As for the advantages noted, cleaner 'in some cases' and filter inspection ease, that's true. However, many also have at least one or sometimes two O-rings that must be removed and new ones lubed and installed with the cartridge. And not all cartridge applications are on the top of the engine, (Toyota under vehicle) which are more advantageous to the inspection, and/or using filter twice. Or using a mightyvac to extract the oil with cartridge on engine top, and not touch drain bolt. Underneath engine cartridges not as beneficial in those situations.
It's also true that it's more expensive per unit for the vehicle manufactures to include the cartridge housing. One member here reported that it was GM iirc that had gone back to spin on from a cartridge in one engine application. I don't look for the spin on type filter to go away any time soon.
While cartridges have some benefits that some like or prefer, having had both, I still prefer the spin on type for ease of installation and removal, spin off, spin on. If using a cartridge though, I much prefer the engine top side type.
