I've used most of these products over the years polishing all aluminum airplanes and found that they are fairly comparable. The big difference in my experience was in the amount of elbow grease used.

One trick an old timer taught me was in the removal of the residue after polishing. He said to use a clean cloth dipped in flour, which I've done for many years now. It seems to take up all of the black residue. You do have to be careful to get up any flour left over that might be in seams or other catch places.
