In those pictures, it looks like the Mobil 1 filter has a silicone anti-drainback valve and the OE filter has a Nitrile rubber. The silicone anti-drain back is good because it can withstand higher temperatures and for a longer period of time. Both have a Nitrile rubber sealing ring. The OE filter does look to have more intake holes and maybe slightly larger holes.

Some filters will have PTFE infused sealing rings or silicone sealing rings. This is nice, but not something I make a main decision maker.

I typically buy Wix, but sometimes I'll deviate to a Motocraft or Purolator. The first thing I look for is the silicone anti-drain back valve. Then, I look at the intake holes of the filter. I pick the one that has the silicon valve and the largest, best shaped or number of holes (the one that looks to have the least flow resistance).

Between that Mobil 1 and the OE, I'd chose the OE. But I am sure someone else makes one similar to the OE, but with a silicone anti-drain back and maybe even a silicone sealing ring. I forget what the Wix I have on car looks like in regards to the intake holes...
