It is easy to say this doesn’t matter, and personally, I couldn’t care less which is used. However, professionally, I have twice in the past two months had a deal with text that was edited by line editor for my organisation, where they strongly criticised our use of these punctuation markers.

And, after much cursing, and my team spending time changing the text, I reflected, and came to like those punctuation markers. Took me a long time, but I have been converted.
