Actually, they are a little worse filtration. But they let more oil thru, because they have less restriction. That's why Wix does not recommend them for street cars. Back years ago,I remember reading Wix developed those filters for the Bush series cars that were not allowed dry sump oiling systems. The Winston Cup cars were running dry sumps, but the Bush cars still mandated spin on stock type filters .
