\textorpdfstring is certainly the better choice because there is no
need to distinguish between section titles and TOC entries, at least
in most cases.

What IMO is more problematic is that section titles are usually
typeset in bold face and math formulas are not.  Thus in most cases
it's better to avoid math in section titles.  There is a similar
problem with typewriter fonts too.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
