That's because back then in 1998, communication was essentially based
on printouts. And I have often read (not being a specialist myself)
that using PK fonts produces better printed quality, compared with PS
- At the time MetaFont is run to produce a PK file (actually a GF
file, turned by gftopk into a PK file), a number of settings can be
performed, optimizing the output for a specific printer. The file /
usr/local/TeXLive/texmf.texlive/metafont/misc/modes.mf contains such
presets for a number of printers.
- By contrast, PS fonts are turned into bitmaps internally by the
printer CPU, which may not provide the same level of control and
William, in case you're listening, is this true?
Now, in the 21st century, communication is more and more based on
reading electronic documents on a desktop or laptop, and for this PS
fonts produce optimum quality and maximum flexibility.
I guess, accordingly, that back in 1998 TeX distributions were
configured by default to use PK fonts whenever available, and that
now they are configured by default to use PS fonts whenever available.

Adobe Acrobat Professional?
Better I don't know, but it provides a number of settings you may
want to play with, when producing a PDF file: whether included JPEG
files must be compressed, which resolution the output should be
optimized for, and so forth.
As for myself, I'm perfectly happy most of the time with Preview,
TeXShop, pstopdf and ps2pdf to produce PDF files from PS files. On
the very rare occasions I had to use Acrobat, I've found the number
of settings it provides more overwhelming for a novice than really
