head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
An early top-down rampage shooter with simple execution demands.

Execution · Practiced Mastery
A golf parody where every hole breaks the rules of golf in a new way.
Postal leans Execution (Practiced Mastery); What the Golf? leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Postal
top-down shooting and movement
What the Golf?
Aim-and-release timing on absurd physics shots
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Postal
enemies use fixed aggressive scripts
What the Golf?
No opponent; every hole is a scripted gag
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Postal
enemy spawn and pathing randomness
What the Golf?
Surprise rule-twists per hole, mapped on first try
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Postal
weapon choice and route clearing
What the Golf?
Learning each gimmick's trick solves the hole
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.
