Its a great question and not easily answered as a ALMS race team may have a different definition of what they want in their high performing oil filter than a Rallye team than a fleet vehicle than a consumer car.
Flow, filter ability, longevity, capacity may all be desired more one of the other depending on application.
For most of us id think you'd want a filter that filters at least as well as OEM and flows at least as well as OEM and can last as long (capacity and durability).
Purolator Boss has a fit for the C8. Incredible reviews on this filter; strongest can, silicon drain-back valve, the best by-pass valve, no cardboard or other crap used in the filter caps or center tube, they're all metal. And the full synthetic filter media is longer than any other filter, meaning it has more pleats. One tester cut the media out of 6 filters and Boss media was longer than any of them. Another tester took apart a Boss with 16,000mi, still in excellent condition...none of the pleats had collapsed in, a sure sign that the media has clogged.

Make sure you contact them to get filter efficiency ratings as they have historically done poorly
I plan to use the AC Delco filter. But I am curious - the title of the thread seemed to suggest a "high performance filter". But most of the discussion seemed to center on the quality and a comparison of filter efficiency. What would be the defining characteristics of a "high performance" filter and why would one even want that? Seems to filter could have a larger capacity and be changed less often but I will be changing at every oil change anyway. It could filter smaller particles - is that even a desirable thing? It could present less resistance but since pressure in the system is regulated anyway seem like that would not have an advantage. So..... what would it be, and why would I want it?
I think for most of those buying "high performance" filters what they're really looking at is perceived build quality. A thicker case is "better" than a thinner one, even if the thinner one will withstand 10 times the pressure it will even need to. Metal internal supports are "better" than plastic ones, even if the plastic ones can withstand temps 2 or 3 times what they'll ever see. A silicone drainback valve is "better" than whatever Delco has, well, because it's silicone. And, of course "synthetic" filtering material must be better than cardboard, even in the absence of any data demonstrating filtering ability. The one thing those pushing high performance filters rarely have is any actual information on filtering capability. And if you choose to use an aftermarket filter, make sure the bypass pressure matches GM's specs, too.
But unless you're running a race engine which is putting stresses on the filter that a street car will never see, the real reason for paying more for a filter is because.... "it costs more, so it must be better, right?"
There are probably hundreds of millions more miles on AC Delco PF64 filters than any "premium" filter, and oil related engine failure just isn't a thing on cars that get the oil and filter changed according to GM's recommendations.

...and this is why I love the Fram Ultra XG filters, and have them in all 3 of my vehicles right now. You can't argue the overall value of the ACDelco filters either considering they can be had for only $3 vs. the $8 for a Fram XG.
