I disagree, there are at least 2 reasons why eps can be better.
a) you can exactly match the fonts in an eps figure to a latex file, which will look much better.
b) you can use \psfrag to change text to get proper mathematics in figures, like gamma2 in an eps becomes $\gamma^2$
c) maybe also, the pstricks package is very nice, but does not work with pdflatex
if pdflatex could do both, I would switch today
but
When I was in academia, I was among the first in our department that moved from latex to pdflatex. One of my motivations was that (E)PS files could be huge, particularly for bitmap graphics, whereas pdflatex supports PNG and JPEG as well as compression of PDF itself. That helped a lot when disk quotas at the time were very limited.
pdflatex doesn't really help here. pdflatex allows you to bypass dvi, the native TeX output format. The input for latex may well still include eps image files though.
True. Of course you can still use EPS, you just have to find another program to view them in. And isn’t there a tool in most TeX pakages that can convert it to PDF, then you should be able to use that at as an input if it makes it easier?
I used to use PDF because you could easily export them from Illustrator and suck them straight in to xelatex or pdflatex (but this was years ago, so I can’t remember all the specifics)
People really should use pdflatex at the very least now. The original latex has too many issues and quirks.
