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

Execution · Practiced Mastery
A dexterity-focused card-cheating game where executing sleight-of-hand maneuvers under time pressure is the primary test.

Execution · Pure Mechanics
Arcade car control across loose surfaces, weather and door-to-door packs.
Card Shark leans Execution (Practiced Mastery); Dirt 5 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.
Card Shark
Cheating gestures require precise timing and sleight-of-hand inputs
Dirt 5
Sliding off-road cars on mixed surfaces is the whole test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Card Shark
NPC marks follow scripted reactions; not truly adaptive
Dirt 5
Pack racing adds light wheel-to-wheel jockeying
Card Shark leans a little harder on variance, though the gap is small.
Card Shark
Card distribution contains some hidden info but is secondary
Dirt 5
Dynamic weather shifts grip unpredictably
Card Shark leans a little harder on optimization, though the gap is small.
Card Shark
Learning optimal cheat sequences and tells is a solvable puzzle
Dirt 5
Car class knowledge and line choice reward study
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.
