Gallilean Moons of Jupiter Moons not to scale
Jupiter has the lion’s share of the big Moon stakes. The consensus is because Jupiter gravitational field is much larger than Saturn’s.
Comparison of Callisto our Moon and Earth
During the early formation of the solar system Jupiter's gravity gathered more leftover material belched out buy the Sun. (this beginning to sound like a Greek tragedy) the new infant moons were able to gather more dust material which lead to the formation of larger moons.
As Jupiter’s moons gathered more mass, friction from the moon’s coming in contact with the left over debris from the birth of the Solar System.
The initial friction resulted in the moons slowing down causing them to be directed towards Jupiter.
The moons were initially made form material left over from our Sun. Jupiter Size had an advantage over the other planets as Jupiter orbited the Sun it gathered more material in its wake.
Over billions of years the spare material was used up. In the early formation of the Solar System the nearby Stella nebulas provided further material so new moons could be formed.
By the time Saturn had formed there was little material left to build more moons , that’s why in part Saturn moons are on average Smaller than Jupiter’s. That’s why Jupiter’s four moons Io, Europa, Callisto and Ganymede are large bodies compared to Saturn who has just one dominant moon Titan.
