Neither... The wood is the fuel, but first it needs to become a gas. The gas is what burns.
When wood burns, it crackles b/c the gas vaporises. If too much gas is in the wood, it will cause a small explosion.
Well is the question the total amount of heat, or total USEFUL heat? In general, a wood fire burns a bit hotter than gas- hence the wood fired pizza ovens. Hoever, gas fireplaces usually have a heat exchanger that draws in room air, warms it, and returns it to the room. It has less air going up the chimney than a wood fireplace (a major point of heat loss) The chimney of a wood fireplace may be more massive brick, which will hold heat after the fire burns out.
