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.

Execution · Practiced Mastery
High-speed cyborg slasher built on precise parries and slicing anything in half.

Execution · Pure Mechanics
Course-corrected revision restoring difficulty to the trilogy's weakest entry.
Metal Gear Rising: Revengeance leans Execution (Practiced Mastery); Ninja Gaiden 3: Razor's Edge leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Gear Rising: Revengeance
parry timing and blade-mode cuts demand sharp reactions
Ninja Gaiden 3: Razor's Edge
Steel-on-bone counters still demand sharp hands
Ninja Gaiden 3: Razor's Edge leans a little harder on reads, though the gap is small.
Metal Gear Rising: Revengeance
bosses telegraph fixed patterns
Ninja Gaiden 3: Razor's Edge
Scripted enemy waves
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Gear Rising: Revengeance
deterministic encounters
Ninja Gaiden 3: Razor's Edge
Deterministic encounters
Metal Gear Rising: Revengeance leans a little harder on optimization, though the gap is small.
Metal Gear Rising: Revengeance
learning movesets and upgrade priorities
Ninja Gaiden 3: Razor's Edge
Simplified systems leave less to solve
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.
