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

Execution · Practiced Mastery
Tests handheld drift-racing execution on short memorisable circuits.

Execution · Pure Mechanics
Island-themed collection of twelve motion-controlled sports showcasing the Wii MotionPlus accessory.
Sonic Drift 2 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.
Sonic Drift 2
Drift timing on tiny Game Gear tracks decides races
Wii Sports Resort
MotionPlus precision in swordplay, archery and bowling
Wii Sports Resort leans a little harder on reads, though the gap is small.
Sonic Drift 2
AI racers follow fixed lines; link-cable duels are rare
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.
Sonic Drift 2
Item pickups add mild race randomness
Wii Sports Resort
Slight physics and CPU pattern randomness
Sonic Drift 2 leans a little harder on optimization, though the gap is small.
Sonic Drift 2
Character choice and track lines have learnable optima
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.
