「と言っても」 vs 「とは言え」


Hi all is it true that
[と言っても](http://jgram.org/pages/viewOne.php?tagE=toittemo) and
[とは言え](http://jgram.org/pages/viewOne.php?tagE=tohaie) are the same thing
except that [と言っても](http://jgram.org/pages/viewOne.php?tagE=toittemo) is for
spoken clauses whereas [とは言え](http://jgram.org/pages/viewOne.php?tagE=tohaie)
is for written clauses?




According to [A Dictionary of Advanced Japanese
Grammar](http://bookclub.japantimes.co.jp/en/title/A%20Dictionary%20of%20Advanced%20Japanese%20Grammar),
と（は）言っても and とは言え are synonymous and interchangeable without changing the
meaning of the sentence. とは言え is used primarily in writing, while と（は）言っても is
used in both written and spoken Japanese.
