Before pdftex appeared Y&Y's dvipsone gave better results with distiller
provided you are working with Type 1 fonts.

The documents I encounter (mostly scientific reports with line art and
color images) generally result in similar sized PDF's. The exceptions
are when images are massaged for screen viewing and documents that place
the same image (logo or slide background) on many pages where more work
is needed to get similar sized files with pdftex.
It would be nice to collect a few cases histories where postscript
workflows are converted to PDF.

We have a collection of figures created with pstricks and other tools.
Most are converted to Adobe Illustrator EPS with the fonts converted to
outline paths. For use with pdftex they can be saved as pdf or converted
with ghostscript or distiller. We deal with some publishers Japan and
elsewhere who need to do things like translating axis lables and
they are all very fond of Illustrator on their ancient Macintoshes.
Maybe in a few years they will be on linux.

Someone mentioned microtype.
Another aspect that is often ignored is the role of
maintainers/developers. Are the very limited resources of the TeX
maintainers/developers are better spent maintaining tools for dvi- or
pdf-based workflows? With dvi, the developers have to deal with the
problems of creating and viewing documents. Who is maintaining .dvi
viewers on Win32 these days? Because pdf is "mission critical" to the
vast majority of people who have never heard of TeX, there are lots of
robust 3rd-party tools to help with a pdf workflow, and TeX maintainers
and developers can focus on a smaller and less system-dependent body of
Finally, while there is some truth to the adage: "If is ain't broke, don't
fix it", just because the train is rolling smoothly down the track at the
moment doen't mean the track will be good around the next corner.
The trend towards more dynamic documents with richer content may create
pressures for massive changes to existing workflows.
