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
Arcade car control across loose surfaces, weather and door-to-door packs.

Execution · Practiced Mastery
Open-world racing MMO spanning a condensed United States.
Dirt 5 leans Execution (Pure Mechanics); The Crew leans Execution (Practiced Mastery).
Dirt 5 leans a little harder on execution, though the gap is small.
Dirt 5
Sliding off-road cars on mixed surfaces is the whole test
The Crew
car control across long cross-country races
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dirt 5
Pack racing adds light wheel-to-wheel jockeying
The Crew
PvP races involve mild positional mind games
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dirt 5
Dynamic weather shifts grip unpredictably
The Crew
traffic and open-world events add noise
The Crew leans a little harder on optimization, though the gap is small.
Dirt 5
Car class knowledge and line choice reward study
The Crew
car specs and route choice are tunable
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.
