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
A round-based tactical shooter decided by aim duels and adapting to humans.

Execution · Competitive PvP
Hardcore team shooter where one bullet kills and the HUD tells you nothing.
Counter-Strike 2 leans Execution (Competitive PvP); Insurgency leans Execution (Competitive PvP).
Counter-Strike 2 leans a little harder on execution, though the gap is small.
Counter-Strike 2
Aim, spray control, and movement are the headline skills.
Insurgency
One-shot lethality rewards precise aim
Counter-Strike 2 leans a little harder on reads, though the gap is small.
Counter-Strike 2
Five humans constantly adapting peeks, fakes, and timings.
Insurgency
Human squads flank and adapt each round
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Counter-Strike 2
Spray RNG and unknown opponent positions add fog.
Insurgency
No killcam or HUD hides enemy positions
Counter-Strike 2 leans a little harder on optimization, though the gap is small.
Counter-Strike 2
Economy, util usage, and map theory are studyable.
Insurgency
Loadout points and objective route knowledge
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.
