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 · Practiced Mastery
A wave-defense game testing reaction speed and upgrade-economy decisions.

Optimization · Pure Optimization
A hybrid real-time and tactical action RPG in a digital city.
Defend Your Castle 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.
Defend Your Castle
Flicking enemies fast matters as waves intensify
Transistor
Real-time and planned hybrid combat.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Defend Your Castle
Enemies follow scripted wave patterns
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.
Defend Your Castle
Enemy spawns randomized but bounded
Transistor
Limited randomness.
Transistor leans a little harder on optimization, though the gap is small.
Defend Your Castle
Spending points on upgrades and units is the strategy
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.
