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

Execution · Practiced Mastery
Simon Belmont's SNES remake-quest with a multidirectional whip and a moody trek to Dracula.

Execution · Practiced Mastery
A Platinum-made cel-shaded brawler where the Autobots fight Megatron with stylish combo combat.
Super Castlevania IV leans Execution (Practiced Mastery); Transformers: Devastation leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Super Castlevania IV
Eight-way whip control and stair commitment test precision
Transformers: Devastation
Platinum dodge-offset timing drives the combat
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Super Castlevania IV
Classic scripted monster patterns
Transformers: Devastation
Decepticons run learnable scripted patterns
Transformers: Devastation leans a little harder on variance, though the gap is small.
Super Castlevania IV
Hidden wall meat, fixed locations
Transformers: Devastation
Random weapon drops shape loadouts
Transformers: Devastation leans a little harder on optimization, though the gap is small.
Super Castlevania IV
Subweapon choice and boss pattern study
Transformers: Devastation
Weapon synthesis, ability builds, boss moveset mastery
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.
