A single pipe across the top minimizes the amount of PVC required. Cheap is always better for me, since DIY is primarily to save money anyway. Airline is much cheaper than PVC. I used clear hose tubing to feed from the pump to the bar; this makes the system a little more flexible than piping.
Also, snaking back and forth like that will result in increased pressure at the bottom, while the top will have considerably less pressure. The differential is much less using the single bar with the airline feeds.
