head to head
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
Milsim 50v50 team-tactical shooter.

Execution · Grand Arena
A tactical hero shooter decided by aim duels and adapting to human opponents.
Squad leans Execution (Competitive PvP); Valorant leans Execution (Grand Arena).
Valorant leans a little harder on execution, though the gap is small.
Squad
Bullet drop, sway, suppression test aim
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.
Squad
Squad tactics versus humans demand prediction
Valorant
Humans constantly adapt peeks, fakes, and ability timings.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Squad
Minimal RNG, comm-driven outcomes
Valorant
Light spray RNG and unknown enemy positions.
Valorant leans a little harder on optimization, though the gap is small.
Squad
Logistics, FOB placement, kit choice deep
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.
