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 Pixar-styled action adventure about a spirit guide cleansing a corrupted forest.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Kena: Bridge of Spirits leans Execution (Practiced Mastery); Red Dead Redemption 2 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Kena: Bridge of Spirits
Parry and dodge timing in boss fights
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Kena: Bridge of Spirits
Corrupted spirits are fully scripted
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Red Dead Redemption 2 leans a little harder on variance, though the gap is small.
Kena: Bridge of Spirits
World is fixed and explorable
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Kena: Bridge of Spirits leans a little harder on optimization, though the gap is small.
Kena: Bridge of Spirits
Rot ability usage and boss pattern learning
Red Dead Redemption 2
Loadouts and routes solvable but loose.
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.
