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.

A hybrid real-time and tactical action RPG in a digital city.
Iron Brigade leans Optimization (Practiced Mastery); Transistor leans Optimization (Pure Optimization).
Iron Brigade leans a little harder on execution, though the gap is small.
Iron Brigade
Manual aiming from your walking trench-mech
Transistor
Real-time and planned hybrid combat.
Transistor leans a little harder on reads, though the gap is small.
Iron Brigade
Tube waves arrive on schedule
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.
Iron Brigade
Loot drops randomize gear options
Transistor
Limited randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Iron Brigade
Turret placement and mech loadout economy
Transistor
Function loadouts have deep optimization.
