head to head
Neither is simply harder - they are hard in different places. Grand Theft Auto V demands more reads; Super Ghouls 'n Ghosts demands more execution.

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

Execution · Practiced Mastery
Arthur's infamous SNES gauntlet of armor-shattering hazards that must be beaten twice with the right weapon.
Grand Theft Auto V leans Execution (Practiced Mastery); Super Ghouls 'n Ghosts leans Execution (Practiced Mastery).
Super Ghouls 'n Ghosts leans clearly harder on execution.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Super Ghouls 'n Ghosts
Committed double jump and relentless hazards punish errors
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Super Ghouls 'n Ghosts
Scripted spawns, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto V
Some mission and lobby randomness.
Super Ghouls 'n Ghosts
Chest contents and zombie spawns add light randomness
Super Ghouls 'n Ghosts leans clearly harder on optimization.
Grand Theft Auto V
Heists, money loops, builds learnable.
Super Ghouls 'n Ghosts
Weapon management and mandatory second loop demand routing
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.
