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 sprawling open-world crime epic with RPG-style character stats across a whole state.

Optimization · Practiced Mastery
Tests patience with scripted encounters and light adventure-game routing.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); The Lord of the Rings: The Fellowship of the Ring leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
The Lord of the Rings: The Fellowship of the Ring
Basic melee, archery and stealth need only modest timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
The Lord of the Rings: The Fellowship of the Ring
Enemies follow simple scripts; nothing adapts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
The Lord of the Rings: The Fellowship of the Ring
Encounters are fixed; little is random once seen
Grand Theft Auto: San Andreas leans a little harder on optimization, though the gap is small.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
The Lord of the Rings: The Fellowship of the Ring
Learning levels, item use and encounter order carries the game
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.
