Axis by axis
Execution6 vs 8
SegaSonic the Hedgehog leans clearly harder on execution.
Half-Life 2
Gravity gun and shooting demand precision.
SegaSonic the Hedgehog
Trackball reflexes dodging hazards at speed decide survival
Reads1 vs 0
Half-Life 2 leans a little harder on reads, though the gap is small.
Half-Life 2
Combine AI scripted, non-adaptive.
SegaSonic the Hedgehog
No opponent, only environmental traps
Variance1 vs 1
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2
Almost no randomness.
SegaSonic the Hedgehog
Hazards are fixed once a course is learned
Optimization3 vs 5
SegaSonic the Hedgehog leans clearly harder on optimization.
Half-Life 2
Linear progression with no builds.

Memorizing the optimal route through each stage helps
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.
