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

Execution · Practiced Mastery
A kart racer testing handling execution under item-driven chaos.

Execution · Pure Mechanics
Island-themed collection of twelve motion-controlled sports showcasing the Wii MotionPlus accessory.
Speed Punks leans Execution (Practiced Mastery); Wii Sports Resort 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.
Speed Punks
Tight kart handling and boost timing decide races
Wii Sports Resort
MotionPlus precision in swordplay, archery and bowling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Speed Punks
Human races add light item mind-games
Wii Sports Resort
Local versus duels involve mild feinting
Speed Punks leans a little harder on variance, though the gap is small.
Speed Punks
Weapon pickups swing positions randomly
Wii Sports Resort
Slight physics and CPU pattern randomness
Speed Punks leans a little harder on optimization, though the gap is small.
Speed Punks
Track shortcuts and item usage have learnable answers
Wii Sports Resort
Each event has small learnable technique optima
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.
