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
The Source-engine era of Counter-Strike's aim-and-economy tactical formula.

Execution · Grand Arena
A tactical hero shooter decided by aim duels and adapting to human opponents.
Counter-Strike: Source leans Execution (Competitive PvP); Valorant leans Execution (Grand Arena).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Counter-Strike: Source
Recoil control and crosshair placement decide duels
Valorant
One-tap aim and crosshair placement decide most duels.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Counter-Strike: Source
Outguessing rotations, fakes, and timing of human opponents
Valorant
Humans constantly adapt peeks, fakes, and ability timings.
Counter-Strike: Source leans a little harder on variance, though the gap is small.
Counter-Strike: Source
Hidden enemy positions until information is gathered
Valorant
Light spray RNG and unknown enemy positions.
Valorant leans a little harder on optimization, though the gap is small.
Counter-Strike: Source
Economy rounds, utility lineups, and map control theory
Valorant
Agent comps, util usage, and economy are studyable theory.
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.
