Not the op, but for me the turboprops I've flown on [0] have a deeper, louder droning noise that really gives me a headache after a while. I think it's personal though, I've spoken about hating them with travelling companions and no one else shares my dislike. I've never actively tried to avoid them though, mainly because I rarely have a choice of time or route when I fly on the airlines I know use them.
