# XeTeX: better using system fonts or packages?

I've recently switched to XeTeX. In my document I use this code to set the fonts:

``````\usepackage[math-style=ISO,bold-style=ISO]{unicode-math}
\usepackage{xunicode}
\usepackage{fontspec}
\defaultfontfeatures{Mapping=tex-text}
\setmainfont{Linux Libertine O}
\setsansfont{Linux Biolinum O}
\setmonofont{Inconsolata}
\setmathfont{XITS Math}
``````

I installed Libertine and biolinium from the ubuntu repositories and I downloaded XITS and installed in my `.fonts` directory... Now I'd like to know what are the main differences between my approach and using the real latex packages (like `libertineotf`.)

Why don't you use the mono font from Libertine? –  Herbert Aug 30 '12 at 16:12
The idea came from here, but actually I don't use mono fonts that much –  justmyfault Aug 31 '12 at 19:58
I guess using the package is seen as a simpler straightforward solution for some users, but, de facto, using one or the other of these won't change the final result. –  user18489 Sep 8 '12 at 3:05
