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

Execution · Grand Arena
A 3D arena fighter where Perception counter exchanges create intense read-off moments between human opponents.

Reads · Grand Arena
A shield-less platform fighter where the absence of defensive options forces constant aggressive reads against human opponents.
Dragon Ball: Sparking! Zero leans Execution (Grand Arena); Rivals of Aether leans Reads (Grand Arena).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball: Sparking! Zero
Perception counter timing and Ki charge positioning demand precise execution
Rivals of Aether
Wavedash movement and off-stage edgeguards require real physical precision
Rivals of Aether leans a little harder on reads, though the gap is small.
Dragon Ball: Sparking! Zero
Perception and counter-burst exchanges are pure human reads
Rivals of Aether
No shields forces constant adaptive prediction against human opponents
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball: Sparking! Zero
Character scaling imbalance adds mild outcome variance
Rivals of Aether
Stage hazards add minor variance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
