According to my experience, the flex/bison combo may appear to be a bit 
simpler to work with but in the end it takes much more work to learn the 
basics and to get it up and running, at least when dealing with relatively 
simple languages.  And things don't get any simpler if you need to maintain 
the parsers (i.e., extend the language, handle parser errors, etc..)

I had a project where I had to develop and maintain a couple of parsers and 
in the end the project became easier to maintain and extend by replacing the 
whole flex/bison mess with a LL parser written by hand (minus the lexer).

YMMV, of course.
