The reasons are

Showa: being the first, great crackling, often considered one of Godzilla's most merciless, intelligent and evil foes (the only other ones to be this is SpaceGodzilla and Destoroyah), love the horns, would win the fight against Godzilla (if the King of the Monsters was alone without any allies) and had destroyed many civilizations (like Venus)

1998: often called Grand King Ghidorah, the Horns, Alien like the original, destroyed the Dinosaurs, cool abilities like that dome

2018: Awesome design, basically called God by the Exif race,  destroyed things like civilizations like Showa

GMK: basically Good Guy, being a undeveloped Yamata no Orochi, awesome revival, being called Thousend Year Old Dragon King Ghidorah, fought Ancient Japanese Warriors, called God of the Sky

Heisei: most used in video games, his transformation imto Mecha King Ghidorah, was three cute little innocent creatures called Dorats
