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
Memorising punishing fixed stages and executing precise run-and-gun inputs.

Execution · Practiced Mastery
Momentum-driven execution over fixed levels rewarding memorised routes.
Journey to Silius leans Execution (Pure Mechanics); Sonic the Hedgehog 3 leans Execution (Practiced Mastery).
Journey to Silius leans a little harder on execution, though the gap is small.
Journey to Silius
Precise jumps and dodges under NES-hard pressure define it
Sonic the Hedgehog 3
Holding speed through fixed hazards demands sharp reactions
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Journey to Silius
Every enemy and boss is rigidly scripted
Sonic the Hedgehog 3
Badniks and bosses repeat identical scripts
Sonic the Hedgehog 3 leans a little harder on variance, though the gap is small.
Journey to Silius
Identical layouts and spawns every attempt
Sonic the Hedgehog 3
Levels never change between runs
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Journey to Silius
Weapon-energy budgeting and pattern memorisation make clears possible
Sonic the Hedgehog 3
Route choice and emerald collection reward memorised play
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.
