Best PDF library

I will be generating PDFs. Which library is the most good?

I have examined so far:

http://www.lowagie.com/iText/
http://libharu.sourceforge.net/

What do you think?

Specially now that macs print to them with ease. Bastards. And I like macs. PDF is like a one way Vagina for your edits [here, personified by the penis]. Use it and the contents of the head won't come out for further use :)
