As ascertained by experiment

I have no reason to think that beef at sixteen dollars a pound is anywhere near twice as good as beef at eight dollars a pound, even if filet mignon does sound a little spiffier than your average ribeye.

(We won't get into the fine points of, say, ground beef at $2.89. And before you ask, this was an impulse purchase, motivated by this very spirit of experimentation and by a projected vacant grilling day.)
