Has anyone seen the Mazda OEM filter cut open? It does not have a top or bottom plate. Not sure that this is good. Also, cellulose as the media is not the best you can get. I would say too that the Micron level is high and would cause wear on the engine.

Which do you think is better?
No doubt a custom-made OEM oil filter is much superior than a “one-size-fit-all” generic aftermarket oil filter which is designed to be used by too many different engines.
SkyActiv-G engines require different oil flow pressure than others without a need of “anti-drainback valve” on oil filter as the oil filter is mounted vertically and the all the oil will be kept in the oil filter and can’t be drained out in any situations. Wix 57002 oil filter is the only legit aftermarket oil filter specially designed for Mazda SkyActiv-G 2.0L / 2.5L. Mazda designed 3 different OEM oil filters for 1.5L、SA 2.0L / 2.5L、and SA 2.5T; but a single after-market oil filter is been called for all 4 engines.
For example, Mobil 1 lists M1-108A as a correct oil filter for Mazda’s 1.5L、SA 2.0L / 2.5L、and SA 2.5T on Mobil website, but principle applications of M1-108A oil filter stated on Mobil website are Hyundai, Kia (1994-10), Infiniti, Nissan (1995-16), Mazda (1990-08, 2011-16), Subaru (2004-15) (Mazda B6Y1-14-302, Subaru 15208-KA010). And Mazda part no. B6Y1-14-302 is an old OEM oil filter used on early Mazda2’s 1.5L mentioned in this Mazda document and it isn’t supposed to be used on any SkyActiv-G engines:
Skyactiv Oil Filters
Here is one MNAO PDF to their US Mazda Dealers concerning genuine Oil Filter(s) installation and use for ALL SA Engines..
Mazda Dealers (in USA particularly) are also seeing stored DTC's (Diagnostic Trouble Codes in PCM) when they use even 'other' genuine Mazda oil filters in Skyactiv engines, see pic, they look identical, but it is what is inside.
About the YouTube video you posted which is criticizing the Mazda OEM oil filter, Thai made Denso 1WPE-14-302 for SA 2.0L / 2.5L, especially to the lack of ADBV. I looked at the comments and he insisted the ADBV is necessary even though the oil filter is mounted virtually. He apparently believed the lack of ADBV will let all oil in the passages drain back to the oil pan through the oil filter and oil pump when the engine is stopped. While his statement may only be partially true as only those oil in higher location passages (valve train) may have some chance to drain back, but Mazda could simply designed a “P-trap” in the oil passages preventing oil draining back by gravity. Mazda engineers should know better from an overall engine design, and believe that it isn’t an issue, and could choose having more room without ADBV in the oil filter for bigger filtering area and higher oil flow on the element. He also made a false observation that the filtering element looks like having gaps on pleats by visal observation from outside, even after a comment pointed out that the sealing is made from inside. He’d never tried to actually open the filter element like many other videos have done. The filter element with no metal end caps in Thai made Mazda OEM Denso oil filter looks like the oil filter cartridge used on my BMW 528i, and definitely there’s no gaps on those pleats.
Since I mentioned the similarity between (Thai made) Mazda oil filter element and BMW oil filter cartridge, if you’re worried about some oil in the passages would totally drain back to the oil pan without ADBV even though there’s full of oil in the filter, then you don’t want to buy a BMW as the oil filter canister on BMW’s famous I6 is sitting at the top of the engine, and it becomes totally empty when the engine is stopped without ADBV. The engine needs some initial time to fill up the oil filter canister which is about 3X bigger than Mazda’s oil filter each time you start the engine. Last time I checked, my 21 years old 2000 BMW 528i still runs fine and uses almost no oil!
The Japanese made Tokyo Roki OEM oil filters and Mexican made Value OEM oil filter are different and do have metal end caps on filter element.
I can only say there’s too much information on the Internet, you make your own decision and trust whoever you think he’s correct.
