"whatever my editor sets it to" is what I would answer, precisely because I've heard the arguments for both sides to death, and I acknowledge that this holy war exists because both sides' arguments have merits. For me, I expect that my team as a group has a rationale for whatever choice is made in the interest of avoiding pointless bikeshedding, but I expect each individual to be adaptable enough that the choice doesn't actually negatively impact their productivity.

Strong opinions loosely held and all that.
