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

Optimization · Practiced Mastery
Tests upgrade economy and lane prioritisation in a defense shooter.

Optimization · Pure Optimization
A hybrid real-time and tactical action RPG in a digital city.
The Culling of the Cows leans Optimization (Practiced Mastery); Transistor leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
The Culling of the Cows
Aimed shots at lanes need modest timing
Transistor
Real-time and planned hybrid combat.
Transistor leans a little harder on reads, though the gap is small.
The Culling of the Cows
Waves are scripted with no adaptation
Transistor
Process enemies follow scripts.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
The Culling of the Cows
Mutation timing adds small surprises
Transistor
Limited randomness.
Transistor leans a little harder on optimization, though the gap is small.
The Culling of the Cows
Upgrade economy and lane priorities are the solvable core
Transistor
Function loadouts have deep optimization.
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.
