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 · Pure Mechanics
Classic arena aim married to champion abilities, tested against adaptive human opponents in fast duel maps.

Execution · Pure Mechanics
Classic arena shooter with faction abilities.
Quake Champions leans Execution (Pure Mechanics); XDefiant 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.
Quake Champions
Champion abilities add execution layers on top of classic rail and rocket aim
XDefiant
Fast arena TTK with no SBMM crutch
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Quake Champions
Human duels require reading opponent ability usage and positioning
XDefiant
Pre-aim and pacing duels reward prediction
Quake Champions leans a little harder on variance, though the gap is small.
Quake Champions
Ability cooldowns introduce mild timing uncertainty per match
XDefiant
Minimal RNG, mostly skill outcomes
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Quake Champions
Champion matchup knowledge and item timing are solvable advantages
XDefiant
Faction abilities and attachments tune fights
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.
