I just spent some time looking at the users' screen shots, from the newest working backwards.
I noticed that everyone seemed to have AmiPDF available on Workbench, but no one had AmiGS.
This interests me because I have noticed that AmiPDF complains a lot about files I want to view, sometimes failing entirely, while AmiGS displays them all, no backtalk. I've been thinking of taking AmiPDF off the Dock so I won't mistakenly launch it.
Looks like they are done by same Author... AmiGS copyright goes to 2008 AmiPDF doesn't have that reference... perhaps AmiPDF is the verson supported now but hasn't got all the bits and pieces from the older AmiGS yet...

There is a certain redundancy/overlap between the two of these apps...
AmiPDF is based on the XPDF engine and seems to do a better job of handling multipage PDF files, in my experience.
AmiGS is solely a wrapper for Ghostscript, which handles all sorts of postscript based formats (.ps, .eps, .epsf and PDF files). Sometimes I've seen AmiGS fail to recognize multiple pages in postscript files (like those made by IBrowse).
Some of the overlap is that AmiPDF uses ghostscript for its printing functionality.
One tip re: PDF's... From time to time, I've come across deviant PDF files that AmiPDF complains about or AmiGS has issues with. Sometimes they can be "fixed" by using the AmiGS (or ghostscript directly, in the CLI) to "re-render" them by "printing" to a PDF file.
