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 · Competitive PvP
Fast aim duels plus predicting human movement on memorised maps.

Execution · Competitive PvP
A beloved movement shooter pairing an execution-heavy campaign with adaptive pilot duels.
Call of Duty: Modern Warfare Remastered leans Execution (Competitive PvP); Titanfall 2 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: Modern Warfare Remastered
Snap aim and reaction time dominate every gunfight
Titanfall 2
Slide-hopping and aim under speed set a high ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Modern Warfare Remastered
Online opponents rotate and adapt; pre-aiming them is prediction
Titanfall 2
Multiplayer pilots out-position and out-guess each other
Call of Duty: Modern Warfare Remastered leans a little harder on variance, though the gap is small.
Call of Duty: Modern Warfare Remastered
Spawns and random lobbies inject per-match noise
Titanfall 2
Flank uncertainty and titanfall timing only
Titanfall 2 leans a little harder on optimization, though the gap is small.
Call of Duty: Modern Warfare Remastered
Map control, loadouts and timing form a learnable meta
Titanfall 2
Campaign gauntlets and loadout synergies are solvable
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.
