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
An explosively destructible run-and-gun starring parody action-movie heroes.

Execution · Pure Mechanics
An endless runner testing reflexes dodging obstacles at accelerating speed.
Broforce leans Execution (Pure Mechanics); Subway Surfers City leans Execution (Pure Mechanics).
Subway Surfers City leans a little harder on execution, though the gap is small.
Broforce
Run-and-gun reflexes amid constant explosions
Subway Surfers City
Swiping to dodge obstacles at speed is the whole game
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Broforce
Enemies are dumb scripts
Subway Surfers City
No opponent; an endless solo runner
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Broforce
Random bro assignments and destructible chaos shake runs
Subway Surfers City
Obstacle patterns are procedurally generated each run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Broforce
Knowing each bro's kit and level layouts helps
Subway Surfers City
Upgrade choices and pickup routing improve high scores
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.
