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 · Practiced Mastery
A frenetic 3DS action shooter mixing rail flight, ground combat, and weapon fusion.

Optimization · Practiced Mastery
An MMO where bar-swap rotations and set-build optimization carry endgame.
Kid Icarus: Uprising leans Execution (Practiced Mastery); The Elder Scrolls Online leans Optimization (Practiced Mastery).
Kid Icarus: Uprising leans a little harder on execution, though the gap is small.
Kid Icarus: Uprising
Stylus aiming through flight and ground combat
The Elder Scrolls Online
Action combat with weaving and rotations
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Kid Icarus: Uprising
Multiplayer Light vs Dark adds human opposition
The Elder Scrolls Online
Cyrodiil PvP adds modest reads layer
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Kid Icarus: Uprising
Weapon drops are randomised
The Elder Scrolls Online
Loot tables and set drops
The Elder Scrolls Online leans a little harder on optimization, though the gap is small.
Kid Icarus: Uprising
Weapon fusion and intensity-wager risk tuning
The Elder Scrolls Online
Rotations, sets, and build theorycraft central
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.
