head to head
Neither is simply harder - they are hard in different places. Grand Theft Auto V demands more reads; SuperHot: Mind Control Delete demands more execution.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.

Execution · Practiced Mastery
Deliberate spatial puzzle-shooting stretched into randomised roguelike runs.
Grand Theft Auto V leans Execution (Practiced Mastery); SuperHot: Mind Control Delete leans Execution (Practiced Mastery).
SuperHot: Mind Control Delete leans clearly harder on execution.
Grand Theft Auto V
Driving and shooting demand decent inputs.
SuperHot: Mind Control Delete
Time-moves-when-you-move still demands precise spatial play
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
SuperHot: Mind Control Delete
Red guys follow simple deterministic behaviour
SuperHot: Mind Control Delete leans clearly harder on variance.
Grand Theft Auto V
Some mission and lobby randomness.
SuperHot: Mind Control Delete
Roguelike runs randomise levels, hacks and spawns
SuperHot: Mind Control Delete leans a little harder on optimization, though the gap is small.
Grand Theft Auto V
Heists, money loops, builds learnable.
SuperHot: Mind Control Delete
Hack synergies and room-clear sequencing reward planning
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.
