Widely regarded as two of the best tracks from Born This Way, Scheiße and Heavy Metal Lover are currently sitting pretty in my iTunes, respectively, as my 4th and 5th favorite songs from Lady Gaga, and also 7th and 8th on my most played songs...not that anyone actually gives a scheiße about my iTunes.
Its hard for me to decide but I ultimately went with hml. I think you should've included bm as those 3 are the fan favorites. I like both but both took me a long time to get into. Both are also overated amongst fans as well.
