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 · Pure Optimization
The genre-defining metroidvania with deep RPG systems.

Optimization · Practiced Mastery
A trap-heavy sequel where level knowledge beats reflexes.

Tomb Raider II leans a little harder on execution, though the gap is small.
Castlevania: Symphony of the Night
Forgiving action combat
Tomb Raider II
Precise platforming plus more frequent gunplay
Castlevania: Symphony of the Night leans a little harder on reads, though the gap is small.
Castlevania: Symphony of the Night
Scripted bosses
Tomb Raider II
Human enemies still run fixed scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Castlevania: Symphony of the Night
Item drops and rare gear
Tomb Raider II
Unknown traps and ambushes punish first runs
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
Tomb Raider II
Route, key-item, and secret solving dominate
