The media companies probably sit back and laugh at all the different brands because they sell the same [censored] to everyone with a different spec name for a wide range of prices.
Steel lid and shell thickness is important for very, very few applications. Threaded plate thickness is pretty standard (except for very few special apps).
Then you're comparing gasket component materials (premium nitrile, basic nitrile, silicone) all of which will last fine & dandy for the duration oil your oil change interval. Plus installation stuff related to good threads, FRAM Suregrip or maybe a hex nut welded to the dome -- whatever you prefer.
So many people are lead & mis-lead by hearsay, generational favorites, and simply what's decent & on sale.
Then you get into the premium synthetic filters like FRAM Ultra, Mobile1, RoyalPurple, etc with synthetic glass media which flows & filters better than anything cellulose and will handle the longer oil change intervals.
I use FRAM Ultra with my synthetic oil, or ToughGuard with semi-syn (depends on what oil is on sale at the time). 94k miles on my truck and 140k on wife's SUV with no issues whatsoever. The filters perform with solid tech support to back it up, and I love the suregrip.
Mobil 1 filters are synthetic blend not all synthetic. Do you have a reference to prove media is made by a couple suppliers and filter companies buy the same thing? I doubt that. My guess is they make their own, and many kinds of qualities for customers based on price.
