In a boxing match maybe.
But in an actual fight, they're in different galaxies.
The power scaling of sailor moon is insane. She has reality warping powers. She has the ability to recreate the entire universe with single attack. Goku doesn't stand a chance.
Magical Girl shows are things like Sailormoon.
The main character is, well, a magical girl. They often need to transform into the magical alter-ego so they can hide in plain sight, and it's definitely not so they could re-use the animation in every episode to save money/waste time.
The sequence is often very dance-like, or almost like a photo-shoot. Very traditionally feminine.
Dragonball-Z was one of the first main-stream anime for boys that was shown on TV in North America.
The main characters are aliens who can turn into a "super" form, and they generally change the way they look during a transformation sequence. It's often just turning blond.
The sequence is often clenching your fists, flexing all of your muscles, and doing a battle-cry.
