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
Hardcore team shooter where one bullet kills and the HUD tells you nothing.

Execution · Competitive PvP
A tactical anime shooter testing aim, dimension-shift movement and round-by-round prediction.
Insurgency leans Execution (Competitive PvP); Strinova 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.
Insurgency
One-shot lethality rewards precise aim
Strinova
Gunfights plus paper-form movement tech demand sharp mechanics
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Insurgency
Human squads flank and adapt each round
Strinova
Round-based PvP rewards predicting rotations and 2D-form fakes
Insurgency leans a little harder on variance, though the gap is small.
Insurgency
No killcam or HUD hides enemy positions
Strinova
Minor spread and ability interaction randomness
Strinova leans a little harder on optimization, though the gap is small.
Insurgency
Loadout points and objective route knowledge
Strinova
Agent kits, economy and site strategy reward study
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.
