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.

Optimization · Pure Optimization
American trucking sim about long hauls and growth.

Optimization · Practiced Mastery
An off-road hauling simulator about planning routes and nursing heavy trucks through mud, ice and rivers.
American Truck Simulator leans Optimization (Pure Optimization); SnowRunner leans Optimization (Practiced Mastery).
SnowRunner leans a little harder on execution, though the gap is small.
American Truck Simulator
Truck handling and trailer parking
SnowRunner
Throttle finesse and winch work prevent disasters.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
American Truck Simulator
No adaptive opponents
SnowRunner
No opponents; terrain is the only adversary.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
American Truck Simulator
Traffic and weather variance
SnowRunner
Mud and ice physics surprise until terrain is learned.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
American Truck Simulator
Fleet, garages, route economics
SnowRunner
Truck loadouts, route planning and fuel logistics decide deliveries.
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.
