General rule is to keep all speakers the same. I think it is much more important that center dialog and left and right be the same, but the importance of making surrounds the same is a little less. That said, I wouldn't get rear speakers that stood out in relation to the fronts. The surround channels are mostly ambience and sounds for effect.
