The spin on filter is the mainstay for all of today's engines. They do such a good job that we can do upwards of 300,000 miles on today's engines. That is in part due to the superior cleaning quality of today's filters. That spring pressure you are talking about is an emergency valve placed there in case of a serious imbalance which, in theory, should never happen.
The 300,000 miles on today's engines has so little to do with which type of oil filter is on it, that it is not significant enough to even mention.
The actual reasons for longer engine life is computer managed fuel injection, electronic ignition (in place of points), and an array of sensors to modulate timing and fuel delivery to account for constant changes in demand.
