My take is flow decreases as the filter is filled with "dirt", so which flows better depends on it's capacity to hold dirt and how long the user leaves it on. When new, filter flow isn't an issue, it's when it fills and the bypass valve starts opening and the oil flows through the bypass hole. I would imagine there is a very wide set of factors determining when each filter fills up, why they say "up to" so many miles. So need to look up the capacity as well, and know your use and engine condition, IMO.
