Hello & welcome,

Which way you should coast depends on the situation: if you can carry all your momentum to go as far as possible, then coast in neutral. It does burn some gas this way, but the momentum you gain will carry you farther/longer and so overall it has a higher MPG.

OTOH, if you have to stop at the bottom of the hill, then you should probably use the engine to brake; especially if your vehicle shuts off the fuel while the wheels are spinning the engine (above a minimum RPM). In this situation, you will get higher MPG by using the engine as a brake.
Sincerely, Neil
