If you live in an area devoid of hills, I'd say driving with load is the best approach. Basically that is keep a moderate throttle, allow the car to speed up a bit on downhills and slow down as much as you can in top gear on the uphills, besides timing lights and watching traffic.
pulse and glide is only beneficial if you're gliding with engine off, or idling VERY slowly, and you can glide for a long time. But if your engine is barely turning in top gear at your desired speed, driving with load is better. Pulse and glide really only improves the mileage on cars with low top gear ratios, ie the engine is spinning very fast when in top gear.
