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 · Pure Mechanics
An open-world winter sports game testing trick execution and downhill control.

Execution · Pure Mechanics
Island-themed collection of twelve motion-controlled sports showcasing the Wii MotionPlus accessory.
Snow leans Execution (Pure Mechanics); Wii Sports Resort leans Execution (Pure Mechanics).
Snow leans a little harder on execution, though the gap is small.
Snow
Controlling tricks, balance and landings is the lead skill
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.
Snow
Open-world solo play with no adaptive opponent
Wii Sports Resort
Local versus duels involve mild feinting
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Snow
Terrain is fixed; minor randomness in events
Wii Sports Resort
Slight physics and CPU pattern randomness
Snow leans a little harder on optimization, though the gap is small.
Snow
Line choice and gear tuning reward planning for events
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.
