Pulse & Glide or In 5th Gear

I'm travelling 70kph, the road is flat, traffic can be either thin or thick.

I can either pulse and glide between 55 & 70kph, or get it to 70 in 5th gear, and not go hard on the pedal (maintain steady throttle position).

An Idling car wastes fuel. In fact, you are better off in gear going down hills, as your car will cut fuel, as it also will in gear and no throttle.

If in neutral, it will still use fuel, but with the engine unloaded (in neutral), the car will glide further - using fuel to idle as it glides.

Which is better, why?

I used to sit in neutral, until I found that if in the right gear, no fuel is used as opposed to Idle fuel in some downhill runs (But there's obviously a choice to be made depending on conditions I guess - in some cases, neutral could work out much better than fuel cut off, or is that the more dominant case, which is why I see so many ecomodder's swearing by Pulse & Glide?)
