Neutral coasting vs In-Gear coasting

Hello all,

I'm somewhat curious as to what people have found with coasting in neutral vs in-gear. For example if you travel down a fairly steep hill, putting the clutch in actually lets the car build up more momentum than having it in gear with no throttle. But is the car actually using more fuel while in neutral than it is when the tires are moving faster than the idle speed of the engine?

Which leads to a follow on from that, if you need to come to a stop is it better to cycle down the gears (engine braking) than to coast in neutral and use the brake?

Cheers!
