Sonic DashvsSubway Surfers
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Sonic Dash
Execution · Twitch Chaos
Reaction-swiping through procedurally assembled obstacle runs.
Subway Surfers
Execution · Twitch Chaos
An endless runner testing swipe reflexes against procedurally generated obstacle streams.
Sonic Dash leans Execution (Twitch Chaos); Subway Surfers leans Execution (Twitch Chaos).

Axis by axis
Execution5 vs 6
Subway Surfers leans a little harder on execution, though the gap is small.
Sonic Dash
Swipe reactions at speed are the entire test
Subway Surfers
Swipe reaction speed at increasing pace is everything
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sonic Dash
No opponent of any kind
Subway Surfers
No opponent - just oncoming obstacles
Variance4 vs 4
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sonic Dash
Procedural track segments keep each run unmemorisable
Subway Surfers
Procedural track segments keep each run unseen ahead
Optimization3 vs 2
Sonic Dash leans a little harder on optimization, though the gap is small.

Upgrade and power-up choices nudge scores modestly
Subway Surfers
Powerup upgrades matter little beyond reflex 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.
