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 · Competitive PvP
A fast-paced online football game emphasizing mechanical ball control and outplaying opposing players.

Execution · Pure Mechanics
Momentum-perfect platform racing spiced with item mind games against humans.
Rematch leans Execution (Competitive PvP); SpeedRunners leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Rematch
tight ball control, shooting, and movement skill
SpeedRunners
Grapple swings and boost timing at full speed decide races
Rematch leans a little harder on reads, though the gap is small.
Rematch
reading human opponents' positioning and passing lanes
SpeedRunners
Timing item throws against human racers' habits wins exchanges
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Rematch
ball physics bounces add minor unpredictability
SpeedRunners
Item pickups add party-game chaos
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Rematch
team formations and tactics are learnable
SpeedRunners
Optimal racing lines per track are learnable
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.
