Not sure that is going to be a fair comparison. Two different ways of shaving here. If you have the technique to use a straight well the the AC is going to be a fine shave. If you don't then the Pils will be.
Nothing revolutionary to add here from me; the PILS is a safety-bar DE. Worst you'll do is irritate your skin or come away with a nick or a weeper. I haven't yet...
As for the AC, well - you could really do some damage with pretty much anything resembling a straight (Durham Duplex aside). Of course, of the replaceable-blade straights, I hear the AC is one of the best. Good weight, great blades. I have a Shavette and it's a bit... cheap.
