I would say with a good in game perspective you would actually do more strafing (at least in cleared spaces while i.e looking for hidden switches) then turning. Of course if the game does not offer hidden switches/doors or Illusion walls then it makes less sense to strafe. Kind of depends on the game.
Personally QE for strafing feels a bit awkward and I need some time to adapt to it.
This discussion somehow reminds me of the "Emacs" vs. "Vi" debates :D
