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 · Pure Mechanics
WWII gunfight execution with light multiplayer prediction.

Execution · Competitive PvP
A wrestling game testing reversal timing with light mind-games against humans.
Call of Duty 3 leans Execution (Pure Mechanics); TNA Impact! leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty 3
Aimbot trivialises both campaign and multiplayer gunfights
TNA Impact!
Reversal timing windows decide most exchanges
TNA Impact! leans a little harder on reads, though the gap is small.
Call of Duty 3
Multiplayer adds modest human positional prediction
TNA Impact!
Human opponents can be baited into whiffed grapples
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty 3
Scripted setpieces and spawn flow add minor unknowns
TNA Impact!
Little is hidden beyond minor AI inconsistency
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty 3
Map knowledge and weapon choice reward light study
TNA Impact!
Move-chain knowledge runs out of depth quickly
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.
