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

Optimization · Practiced Mastery
A first-person action RPG where ability builds and parry timing share the load.

Execution · Practiced Mastery
Open-world western about an outlaw forced to hunt down his old gang.
Avowed leans Optimization (Practiced Mastery); Red Dead Redemption 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.
Avowed
First-person action, parry and dodge timing
Red Dead Redemption
Dead Eye softens but gunplay still wants aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Avowed
Scripted enemies
Red Dead Redemption
Multiplayer skirmishes add light human prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Avowed
Loot rolls and enchant drops
Red Dead Redemption
Ambient events and spawns vary mildly
Avowed leans a little harder on optimization, though the gap is small.
Avowed
Builds, companion synergy, ability planning
Red Dead Redemption
Mission approaches and economy are learnable
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.
