It depends on priorities and possibilities. On a matter of principle, I
am the kind of guy who would always go the Apple way when there is a
viable Apple alternative. However, as regards pstopdf (Panther's
Distiller) against ps2pdf (GhostScript's Distiller) or epstopdf
(teTeX's Distiller script based on ps2pdf), there may be situations
when GhostScript seems definitely more appropriate, though Panther will
always give the higher-quality result.
A real-life example: last night I finalized a research proposal
including, for illustration, a figure taken from a reference article.
The article was available electronically as a scanned PDF file. The
page containing the figure was extracted from this file using Adobe
Illustrator, and then cropped, to only include the figure, using
Preview. However, the way Preview crops an image is simply by hiding
the rest of the image (I think technically that's altering the
MediaBox), but this rest stays here and may confuse XeTeX or pdfTeX
when including the PDF file. Thus, I ended up using Adobe Acrobat to
convert the cropped PDF file to EPS and fix the bounding box in the
process. Only drawback: the cropped PDF file was about 100 kB, and the
EPS file 10.6 MB!
Using finally epstopdf (GhostScript's Distiller) to convert the EPS
result to PDF, I ended up with a 100 KB file, while using pstopdf
(Panther's Distiller) I ended up with a 1.5 MB file. Which makes some
difference indeed, though the visual quality of the two PDF files seems
Of course there are counter-examples too: last year I wrote a paper
with XeTeX, which contained some PDF figures resulting from the
conversion of EPS files. I never could get a satisfactory result when
using epstopdf for the conversion (I don't remember exactly how, but
the figures were shaken up by the inclusion in the XeTeX file), while
when using pstopdf the output was perfectly OK.
Thus I would recommend always trying the two alternatives, and see what
comes out best. Which means, in practical terms, for those having
installed TeXShop: take the original EPS file, drag it onto TeXShop on
one side (this will use GhostScript to create a PDF version) and drag
it onto Preview on the other side and save the output (this will use
Panther to create another PDF version), try including both versions in
your TeX document, and see which one comes out best.
