1) Welcome to the site!
2) Unless you do a good job of defining your terms, you're going to get a WIDE variety of answers
3) Without a HUGE amount of time and money, it's difficult for anyone to prove what would be "best" for any particular application
Just about any filter you guys carry will do a fine job. Don't get all hung up on what's "best" because there are many good filters, and even the "normal" ones are more than up to the task.
Much depends upon how often you O/FCI, but presuming you're the typical person, then any standard Fram, Purolator, etc will do a decent job. You can spend more, but there is no credible study that shows a direct correlation to the efficiency and actual wear in real world use. The infamous GM filter study (now a few decades old) was grossly biased and not at all applicable to real world use, and anyone who's ever actually READ the study, rather than just pass on internet rhetoric, understands that. And anyone who'd have a differing opinion is welcome to speak up, but I'll ask you bring PROOF and not conjecture based upon some beta lab test.
The reality is that once a minimum reasonable threshold is passed for efficiency, any gain responds to a very aggressive law of diminishing returns. You can spend a lot more on a super-premium filter, but you'll not notice your equipment lasting any longer or running any better in a way that can be tangibly proven. Therefore, a "normal" filter is all one needs for "normal" O/FCIs.
