Easy peezy oil changes with the Fumoto drain valve or tiny bit of added protection with a magnetic drain plug?? 

A drain plug with a real rubber gasket/o-ring and not some crappy one time use crush thing.
I use copper or aluminum drain plug washers. They never wear out.A drain plug with a real rubber gasket/o-ring and not some crappy one time use crush thing.
The valves on both my Jeep and my Toyota are well protected. On the Jeep it's up inside, well protected by the skid plate. And on the Toyota, the cover you have to remove protects everything. Pan, valve, and oil filter.Plug hands down. Too much crap can fly up from the road to hit any aftermarket valve and damaging it IMO. It's a critical component, crap happens.
