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.

Optimization · Pure Optimization
Co-op LEGO brawler where unlocking the right character to grab every collectible is the game.

Optimization · Practiced Mastery
A gag-driven platformer testing little beyond collectible patience.
LEGO Batman: The Videogame leans Optimization (Pure Optimization); The Simpsons Game leans Optimization (Practiced Mastery).
The Simpsons Game leans a little harder on execution, though the gap is small.
LEGO Batman: The Videogame
Button-mashy combat with no real fail state
The Simpsons Game
Simple platforming and character-power timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
LEGO Batman: The Videogame
Scripted goons and bosses
The Simpsons Game
Parody enemies are jokes on rails
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
LEGO Batman: The Videogame
Stud and brick locations fixed
The Simpsons Game
Levels are fixed gag sequences
LEGO Batman: The Videogame leans a little harder on optimization, though the gap is small.
LEGO Batman: The Videogame
Character-ability gating drives collectible completion
The Simpsons Game
Character-ability puzzles and collectibles are lightly solvable
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.
