Recently I decided to be a bit more scientific, and bought 4 types, with different degrees of fineness.
A copper sheet was used for the test. Sterling would have been better, but I can't afford to sacrifice that much to science.
6444 Medium
7447 Very Fine
7448 Ultra Fine
7445 Super Fine
I use the 7448 Ultra Fine for most work, and the 7447 Very Fine for some basic scratch removal beforehand, should the work need it. I don't see a big difference between the 7447 and the 6444 Medium in terms of scratch pattern. I have used the 7445 Ultra Fine before polishing to good effect once or twice. Anyway, I mostly documented this so I could remember which pad is which, as the Very Fine and Medium pads look a lot alike (one is maroon, the other brown), and there are no intelligible markings on the pads themselves.
You can even use them to clean your pots and pans!
UPDATE:
Here is the color of each pad in order from coarse to fine:
6444 Brown Medium
7447 Maroon Very Fine
7448 Light Grey Ultra Fine
7445 White Super Fine

Cool! But...which pad is which color?
Oh yeah, I should have put that...
editing the post in a second...
How do you use the 7445 White Super fine (i.e. how are you actually doing the polishing - just rubbing?)
I've tried using 7445 on 6061 aluminum and it doesn't seem to make a dent (whereas 7447 does a great job, but isn't quite as "fine" as I would like)
Yes, just rubbing. Depending on how much surface area you are applying pressure on, you get different scratch patterns (heavy/light). I found that first using a coarser pad (7447) and then using the white (just as with sandpaper) helps get a finish, alone (unless on a polished surface) the white won't remove any heavier scratches.
