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.

Optimization · Systems & Chaos
An ARPG loot grind about chasing affix rolls to feed a damage-stack build.

Optimization · Systems & Chaos
A free Vampire Survivors-style horde shooter starring Hololive VTuber idols.
Diablo IV leans Optimization (Systems & Chaos); HoloCure: Save the Fans leans Optimization (Systems & Chaos).
HoloCure: Save the Fans leans a little harder on execution, though the gap is small.
Diablo IV
Clicking and dodging are light; gear carries you.
HoloCure: Save the Fans
Kiting hordes takes moderate positioning skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Diablo IV
Enemies and bosses are scripted; no adaptive opponent.
HoloCure: Save the Fans
Fan swarms mindlessly chase, never adapt
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Diablo IV
Loot rolls, affixes, and uniques drive every session.
HoloCure: Save the Fans
Random upgrade offers and enemy spawns
Diablo IV leans a little harder on optimization, though the gap is small.
Diablo IV
Paragon, aspects, and damage buckets are solvable theorycraft.
HoloCure: Save the Fans
Weapon collabs and stamp builds are solvable synergies
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.
