I should have asked how you define best?
longevity?
robust construction?
price?
filtration?
flow?
uniqueness?
The Ac/Delco filter is a good all around filter, but others lead in some of the above categories.

a year or so ago there was a thread on this and someone put up a link to testing that showed Purolator was one of the top filters, PureOne PL12222, I tried one and agree, it's only a buck or two more expensive than AC, and a few bucks less than Mobil1 and other popular alternatives to AC. Now I use them on all my cars.
One thing to be careful of, many filters are sold under a brand name but jobbed out to someone else to build, the design often changes to whomever builds it cheapest. And for you racer types, if it is good enough for Jimmie Johnson, it should be good enough for you. Check out the history of the company.

Filters are not like shocks or tires. You don't know how good works until it is no late....

Take a look at-

Has a lot of good information on oil filter studies. Read it and be your own judge.

LOL) and the motor that it's protecting gets rebuilt again afterwards. 
My filter stays in for far more than 500 miles and I am neither changing it nor rebuilding my motor after every track visit.

True, but then again Jimmie Johnson's filter only has to hold together for 500 miles or less (though yes, it is at a nearly constant 9k rpms LOL) and the motor that it's protecting gets rebuilt again afterwards.

Would appreciate it if anyone considering the AMSOIL Ea Oil Filter drop me a PM so I can ensure you get the best pricing possible via the AMSOIL Preferred Customer Program.
FYI, I used the AMSOIL EAO32 in my LS2 Cadillac CTS-V until I recently sold it and my used oil analysis reports showed wear well below the labs average.

The 6/10/07 sample was Mobil 1 and AC Delco, the rest AMSOIL 0w30 and EAO32.
