Quite honestly, the brand of filter you choose doesn't really
matter all that much. Sure, there may be some differences in the type or amount of filter medium they use, how it's packed inside the case, the amount of pressure they're rated for, the color and labeling of the damn thing... but the real benefit you get is replacing the oil and
the filter on a regular basis. When it comes down to it, they all pretty much do what they're supposed to do - filter out some debris. What they can't do is filter out water - condensation that builds up inside your engine when it's turned off. I'm pretty convinced that most of the arguments you'll hear will be based on some test where one filter out-filtered another by however many particle bits or maybe one can hold a bit more pressure than the rest or someone cut them apart and measured the amount of filter material and one had slightly more than the rest or they like they way certain ones are packed inside the case or some filter material can hold slightly smaller particles than the rest... etc.
Other than that, many arguments will be from people who have used whatever filter for however many years and they're emotionally attached to them because they haven't failed on them yet or because they can get them super cheap and they're convinced they work just as well as the rest - actually, both of those apply to me with my precious OEM filters
