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

Optimization · Systems & Chaos
Guided detective clue-hunting with hidden answers and minimal challenge.
Little Busters! leans Variance (Light / Casual); Murdered: Soul Suspect leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.

Murdered: Soul Suspect
Walking and clue-clicking; demon stealth is trivial
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
