head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
Columbia's sky-rail shooter wrapped in dimensional intrigue.

Execution · Practiced Mastery
An open-zone Sonic experiment with cyberspace stages.
BioShock Infinite leans Execution (Practiced Mastery); Sonic Frontiers 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.
BioShock Infinite
Skyline traversal and aiming reward inputs.
Sonic Frontiers
Boost-running and combat at speed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
BioShock Infinite
Enemies scripted in arena waves.
Sonic Frontiers
Scripted enemies
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
BioShock Infinite
Loot drops mildly randomized.
Sonic Frontiers
Static open zones
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
BioShock Infinite
Gear, vigors, weapon picks straightforward.
Sonic Frontiers
Skill tree and stat farming
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.
