I'm currently typesetting my lecture notes for classical electrodynamics using the
tufte-book class and XeLaTeX.
This is my first time using XeLaTeX and so I stumbled upon the two packages
mathspec, when it came to include an OpenType math font (here TeX Gyre Pagelle Math).
I browsed the documentation of the two packages a little bit, but wasn't able to find out, which is the "better practice" to use.
Question: Should I use
mathspec for my XeLaTeX documents?
