Additional to what Till already pointed out.
The packages pst-text, pst-func, pst-fractal. pst-solides3d,
and pstricks-add (the differential equation part)  are
difficult to realize with tikZ. On the other hand PSTricks
is not able to tell TeX the size of the bounding box of the
image, which could be very useful for typesetting additional
text, like labels, etc
