Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

A simple licensed brawler testing little beyond button mashing and upgrades.

Execution · Practiced Mastery

Dragon Ball Z: Sagas
Simple brawling needs only basic timing
Fighting Force
Crowd control and weapon swings need basic timing
Fighting Force leans a little harder on reads, though the gap is small.
Dragon Ball Z: Sagas
Enemies and bosses are scripted
Fighting Force
Enemy waves attack in fixed patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball Z: Sagas
Linear levels with fixed encounters
Fighting Force
Levels and pickups are static
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball Z: Sagas
Z-coin upgrades add a thin progression layer
Fighting Force
Route choices and weapon use are shallow systems
