head to head
Montaro : RE asks more than Subway Surfers, and the gap is execution.

Execution · Pure Mechanics
A comedic reflex platformer testing jump timing against fast obstacles.

Execution · Twitch Chaos
An endless runner testing swipe reflexes against procedurally generated obstacle streams.
Montaro : RE leans Execution (Pure Mechanics); Subway Surfers leans Execution (Twitch Chaos).
Montaro : RE leans clearly harder on execution.
Montaro : RE
Reflex jumping and timing carry this runner-platformer
Subway Surfers
Swipe reaction speed at increasing pace is everything
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Montaro : RE
No adaptive opponent in a solo arcade game
Subway Surfers
No opponent - just oncoming obstacles
Subway Surfers leans a little harder on variance, though the gap is small.
Montaro : RE
Some procedural obstacles add randomness
Subway Surfers
Procedural track segments keep each run unseen ahead
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Montaro : RE
Little to solve beyond reacting to obstacles
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.
