There are several ways to get from a TeX source file to a PDF file using LaTeX:
LaTeX to
dvitopdf(viadvipdfordvipdfmordvipdfmx).LaTeX to
dvitopstopdf(viaDviPsfollowed byps2pdf).pdfLaTeX.
Is there an advantage to using any of the first two over the third?
does the fact MikTeX use XeLaTeX to crete all of these make any difference?
MikTeX ships XeLaTeX, but pdfLaTeX is just pdftex with the pdflatex format, versus XeLaTeX, which is xetex with the xelatex format. I've never heard of a way to use XeLaTeX with pdfLaTeX.
