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

Execution · Competitive PvP
Melee-focused battle royale.
Call of Duty: Modern Warfare 2 leans Execution (Competitive PvP); Naraka: Bladepoint leans Execution (Competitive PvP).

Call of Duty: Modern Warfare 2
Fast time-to-kill rewards raw aim and reflex
Naraka: Bladepoint

Naraka: Bladepoint leans a little harder on reads, though the gap is small.
Call of Duty: Modern Warfare 2
Outguessing human rotations and flanks
Naraka: Bladepoint
Sword duels are pure adaptive mind games
Naraka: Bladepoint leans a little harder on variance, though the gap is small.
Call of Duty: Modern Warfare 2
Spawn flips and killstreak randomness
Naraka: Bladepoint

Call of Duty: Modern Warfare 2
Killstreak economy, loadout and map knowledge
Naraka: Bladepoint
Hero abilities and weapon synergies
