head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Pure Mechanics
Arcade car control across loose surfaces, weather and door-to-door packs.

Execution · Pure Mechanics
An arcade kart racer testing drift handling and stunt execution.
Dirt 5 leans Execution (Pure Mechanics); Joy Ride Turbo leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Dirt 5
Sliding off-road cars on mixed surfaces is the whole test
Joy Ride Turbo
Precise drifting and stunt timing decide races
Joy Ride Turbo leans a little harder on reads, though the gap is small.
Dirt 5
Pack racing adds light wheel-to-wheel jockeying
Joy Ride Turbo
Some anticipation of human rivals in multiplayer
Joy Ride Turbo leans a little harder on variance, though the gap is small.
Dirt 5
Dynamic weather shifts grip unpredictably
Joy Ride Turbo
Item pickups and track hazards add minor chaos
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dirt 5
Car class knowledge and line choice reward study
Joy Ride Turbo
Racing lines and car unlocks reward planning
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.
