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

Execution · Practiced Mastery
A mobile kart racer testing simple line-holding against upgrade-gated progression.

Execution · Practiced Mastery
Vehicular mayhem testing car handling plus knowing when wrecking beats racing.
Angry Birds Go! leans Execution (Practiced Mastery); Carmageddon II: Carpocalypse Now leans Execution (Practiced Mastery).
Carmageddon II: Carpocalypse Now leans a little harder on execution, though the gap is small.
Angry Birds Go!
Steering and boost timing decide downhill races
Carmageddon II: Carpocalypse Now
Perfect car control trivialises wrecking AI opponents and surviving
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Angry Birds Go!
Opponent karts run rubber-band AI, nothing to model
Carmageddon II: Carpocalypse Now
AI drivers follow set behaviours, never modelling the player
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Angry Birds Go!
Power-up rolls inject mild chaos
Carmageddon II: Carpocalypse Now
Pickup spawns and physics chaos add modest run-to-run noise
Carmageddon II: Carpocalypse Now leans a little harder on optimization, though the gap is small.
Angry Birds Go!
Kart upgrades and racing lines dominate progression
Carmageddon II: Carpocalypse Now
Choosing wreck-versus-race strategy and upgrade economy is solvable
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.
