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.

The genre-defining metroidvania with deep RPG systems.

Optimization · Pure Optimization
A transgressive stealth horror game about an asylum escapee executing hunters from the shadows.
Castlevania: Symphony of the Night leans Optimization (Pure Optimization); Manhunt 2 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.
Castlevania: Symphony of the Night
Forgiving action combat
Manhunt 2
Execution-hold timing and stealth movement need steady hands
Castlevania: Symphony of the Night leans a little harder on reads, though the gap is small.
Castlevania: Symphony of the Night
Scripted bosses
Manhunt 2
Hunter AI patrols on fixed search scripts
Manhunt 2 leans a little harder on variance, though the gap is small.
Castlevania: Symphony of the Night
Item drops and rare gear
Manhunt 2

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Castlevania: Symphony of the Night
Build crafting and sequence breaks
Manhunt 2
Shadow routes and lure setups make levels solvable puzzles
