Distance behind the listener is also key. The farther back a speaker is, the less you will really detect its exact location. If the distance is shorter, go with the QS series, otherwise i say it matters less.
Odd configurations would fare better with the QS as well.

Unless your intent is to put the speakers on the side walls and in such case, QS series, which by your earlier post, it sounds like this is the intent.
