BlurvsF1 Race Stars
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Blur
Execution · Pure Mechanics
Arcade racing with Mario Kart-style power-ups bolted onto licensed cars.
F1 Race Stars
Execution · Twitch Chaos
Kart-racing control with item RNG swinging family-friendly races.
Blur leans Execution (Pure Mechanics); F1 Race Stars leans Execution (Twitch Chaos).

Blur leans a little harder on execution, though the gap is small.
Blur
Racing lines and dodging shots demand car control
F1 Race Stars
Kart handling and boost timing decide clean laps
Reads3 vs 3
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Blur
Human racers bait and time power-ups against you
F1 Race Stars
Human racers feint and time item attacks in multiplayer
Variance4 vs 4
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Blur
Power-up pickups and incoming attacks add chaos
F1 Race Stars
Item rolls swing positions like any kart racer
Optimization4 vs 3
Blur leans a little harder on optimization, though the gap is small.
Blur
Track knowledge and pickup routes are learnable
F1 Race Stars
Track shortcuts and KERS timing are learnable edges
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.
