I havnt had either of those rooms, but we prefer Aft (back ) over the front.
Less motion back there and closer to the buffet and drink station on deck 9. no need to wait for the elevator, just up one flight and your there.
here is a site with room reports,maybe there will be a report on those rooms that may help you.
