head to head
Neither is simply harder - they are hard in different places. Garry's Mod demands more optimization; Genital Jousting demands more execution.

Reads · Light / Casual
Source-engine sandbox whose community modes range from building to social deduction.

Execution · Competitive PvP
A deliberately chaotic party game where laughter beats skill.
Garry's Mod leans Reads (Light / Casual); Genital Jousting leans Execution (Competitive PvP).
Genital Jousting leans clearly harder on execution.
Garry's Mod
Varies by mode; base sandbox is undemanding
Genital Jousting
Floppy physics controls demand some clumsy coordination
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Garry's Mod
Social deduction modes like TTT involve humans
Genital Jousting
Human party opponents are loosely predictable between laughs
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Garry's Mod
Hidden roles and player chaos in popular modes
Genital Jousting
Chaotic physics randomise most outcomes
Garry's Mod leans clearly harder on optimization.
Garry's Mod
Contraption building rewards systems knowledge
Genital Jousting
There is barely a system to solve - by design
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.
