If I need a figure for a document I usually use TikZ or PSTricks. Sometimes I would like to promote it to other people who usually use only GUI programs for such kind of stuff. But then I restrain myself and don't promote anything because I have the feeling that I don't have good objective arguments which the other person can understand.
For me it is
- I have the feeling to have complete control over everything when using TikZ/PSTricks over any GUI tool.
- I can create commands which take parameters as argument and return a figure depending on the argument.
- It gives me a consistend look in a LaTeX document (same fonts, fontsizes,...).
- There is a very friendly, active community out there (TeX.SX) where I can get help on most of my questions. :-)
- It's just fun.
However I feel this is not convincing enough for a typical GUI user and I feel that one can get those things also using GUI programs (though I don't know how).
So are there better or clearer objective reasons to prefer TikZ or PSTricks over any GUI driven program. Do you have some good examples which illustrates the basic advantages of those command line driven tools in some way dramatically?
