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 · Practiced Mastery
Cornering execution over memorisable circuits, with light prediction in wheel-to-wheel multiplayer.

Execution · Practiced Mastery
A modern beat-em-up where precise combo execution and enemy-pattern mastery are the skill ceiling.
Grid 2 leans Execution (Practiced Mastery); Streets of Rage 4 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.
Grid 2
Car control through corners is the entire moment-to-moment test
Streets of Rage 4
Precise combo strings, parry timing, and star-move usage are decisive
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grid 2
Online wheel-to-wheel adds light positional prediction
Streets of Rage 4
Enemies use scripted attack patterns; no adaptive opponent
Streets of Rage 4 leans a little harder on variance, though the gap is small.
Grid 2
Tracks are fixed and fully visible
Streets of Rage 4
Enemy arrangement is largely fixed; minimal RNG
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grid 2
Racing lines, braking points and car selection are studyable
Streets of Rage 4
Character selection, route sequencing, and score management reward study
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.
