Now that Xe(La)TeX is being increasingly used to deliver nifty documents, I am wondering if any recommendations have been published or discussed about the best combination of font families for mixing Serif, Sans Serif, and Monospace.
For example, I know that Kieran Healy uses a nice combination of Minion Pro, Myriad Pro, and Pragmata (a LaTeX template is available at kjh-vita). Likewise, according to the American Association of University Presses, Minion, ITC New Baskerville and FF Scala & 4. FF Scala Sans are the top three best fonts, but see
Top Typefaces Used by Book Design Winners. I have been playing myself with Apple Garamond, Fontin Sans and Menlo (Apple default monospaced font shipped with OS X 10.6), because all are available with any combination of
\bfseries (as described in The XeTeX Companion).
So my question is just: What would you recommend as pretty looking and freely available fonts for typesetting a TeX or LaTeX document? Ideally, this should allow to use mathematical expressions as well. (one response per post please)
