Now on the Mercedes where the oil filter is up top, an extractor would make more sense (to me).

The biggest issue with extractors is that many engines will not work with them as the dipstick run is hampered by lower-end baffling or a crazy bend of some sorts. There are a lot of American cars where it will not work (crazy Americans).
On one of the oil threads (I believe AK's) I did a comparison of what the extractor removed versus just the drain plug, and I think I was able to get eight (8) more ounces out. This is also one of the benefits of extractors, but not on all engines. You can typically get the tube to a lower point in the oil pan than the lowest point of the drain plug.
