Neither, both have been known since antiquity. He did discover the moons orbiting Jupiter as well as craters on the Moon. In antiquity, there were seven "wanderers" in the sky (moving lights vs stars that didn't move). They were Mercury, Venus, Mars, Jupiter, Saturn, the Moon, and the Sun. This is where we get the days of the week

Galileo did not discover Jupiter or Saturn. They are naked eye objects that have been known throughout history. He did discover the 4 largest satellites of Jupiter which helped support the Sun-centered universe. On Saturn he discovered the rings of Saturn although he originally though the rings were two smaller planets on either side of the main body.
He also discovered the phases of Venus and craters on the Moon. All of these amazing discoveries resulted because he was the first to to point a telescope into the heavens.

He didn't discover either. Both were known to ancient astronomers and anyone that cared to watch the night sky.
What Galileo did discover were the 4 large moons of Jupiter around 160 AD, using the newly-invented telescope.

Jupiter.
Perhaps Galileo's most famous discovery came when he pointed his telescope at Jupiter. Aside from seeing the disk of the planet, he also saw four dots of light accompanying it. Over the course of a few nights, these dots changed position with respect to Jupiter, which Galileo recognized to mean that they were moons orbiting the giant planet.

Jupiter was already known to be a planet or "wanderer". However, through use of that Dutch invention, the telescope, he discovered what are now referred to as the "Galilean moons" of Jupiter: Ganymede, Callisto, Io, and Europa.

Saturn has been known since antiquity since it's visible to the naked eye. Galileo was the first to look at it through a telescope.
