I would say whichever you like the sound of. Get a demo with your AV receiver (or your intended AV receiver) and compare the front left and right with music you know well. This will tell you much more about the differences between the two than surrounding yourself with speakers and trying them out with film clips. You may find one pair sound much better with your receiver than the other, if not just from a technical point of view, more from a synergistic point of view.
