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 · Pure Mechanics
First-person physics platformer about leaping across a convoy of crashing trucks.

Execution · Practiced Mastery
The 1981 arcade classic of climbing girders and dodging barrels.
Clustertruck leans Execution (Pure Mechanics); Donkey Kong leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Clustertruck
Frame-tight jumps across moving trucks
Donkey Kong
Frame-tight jumps over barrels under arcade pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Clustertruck
No opponent
Donkey Kong
Fixed arcade patterns, nothing adapts
Clustertruck leans a little harder on variance, though the gap is small.
Clustertruck
Physics chaos makes truck piles unpredictable
Donkey Kong
Barrel bounces add slight unpredictability
Donkey Kong leans a little harder on optimization, though the gap is small.
Clustertruck
Route lines and ability use for speedruns
Donkey Kong
Stage patterns and score routes fully learnable
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.
