Building comparison
head to head
Need for Speed: RivalsvsSonic Forces: Speed Battle
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Need for Speed: Rivals
Execution · Pure Mechanics
Open-world racer where banking risky speedpoints against human cops drives the tension.
Sonic Forces: Speed Battle
Execution · Twitch Chaos
A mobile racing runner testing reflex lane-play under item RNG and upgrade grind.
Need for Speed: Rivals leans Execution (Pure Mechanics); Sonic Forces: Speed Battle leans Execution (Twitch Chaos).

Axis by axis
Execution7 vs 6
Need for Speed: Rivals leans a little harder on execution, though the gap is small.
Need for Speed: Rivals
Open-road control with pursuit tech timing
Sonic Forces: Speed Battle
Lane-switch timing and trap dodging decide races
Reads2 vs 2
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Need for Speed: Rivals
AllDrive mixes human cops and racers in
Sonic Forces: Speed Battle
Live opponents exist but interaction is mostly indirect items
Variance3 vs 4
Sonic Forces: Speed Battle leans a little harder on variance, though the gap is small.
Need for Speed: Rivals
Dynamic open-world encounters and weather
Sonic Forces: Speed Battle
Item rolls and character gacha swing outcomes
Optimization4 vs 4
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Need for Speed: Rivals
Risk-versus-bank speedpoint economy
Sonic Forces: Speed Battle
Character upgrades and route knowledge compound over time
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.
