KG-12 or Patchout?

[KMart]

For a while I have been using the KG-12 for cleaning up any copper fouling. It seemed to do an excellent job, but as with different things, I recently bought some Patchout. I used some of the Patchout the other day and I am not sure what I think at this point.
I am not using the accelerator with the Patchout and it sure seems to take longer than the 20 minutes the instructions.
For those of you that have used both, what are your thoughts?

In my limited testing KG-12 doesn't get any copper out after I use Patchout.

According to this "soak a bullet and see how much it weighs after" test, both KG-12 and Patch-out (with the accelerator) seem to work pretty well on copper.
