I will say that, in the last decade or so, we have seen some real issues in the automotive industry with using many aftermarket oil filters. For example, Fram filters were, at one time, a most trusted brand. But, the quality in that brand has been questioned by many mechanics and shops after researching lubrication failures in engines that were ultimately blamed on filter failure.
I have a good opinion of NAPA brand filters and don't know of any lack of quality testimonials regarding them. But I don't use them regularly and, like many techs I know of that work on Ford vehicles that recommend ONLY OEM filters for that line's latest engines, maybe your mechanic has seen something we haven't.
I use and trust WIX brand oil filters on all the engines I have based on evaluations I have read regarding materials and performance including bypass and anti drain back valves.
