head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Practiced Mastery
A 1979 mini-golf simulation testing timing and distance judgment.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Miniature Golf leans Execution (Practiced Mastery); Red Dead Redemption 2 leans Execution (Practiced Mastery).
Miniature Golf leans a little harder on execution, though the gap is small.
Miniature Golf
Timing and aiming the putt is the core skill
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Miniature Golf
Solo or alternating play, no opponent to read
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Miniature Golf
Fixed obstacles, little randomness
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Miniature Golf leans a little harder on optimization, though the gap is small.
Miniature Golf
Judging angles and distance for each hole is solvable
Red Dead Redemption 2
Loadouts and routes solvable but loose.
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.
