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
A classic multiplayer deathmatch shooter distilled to pure arena combat.

Execution · Competitive PvP
Hardcore team shooter where one bullet kills and the HUD tells you nothing.
Deathmatch Classic leans Execution (Competitive PvP); Insurgency 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.
Deathmatch Classic
aim and movement decide every fight
Insurgency
One-shot lethality rewards precise aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Deathmatch Classic
human opponents predict positioning and timing
Insurgency
Human squads flank and adapt each round
Insurgency leans a little harder on variance, though the gap is small.
Deathmatch Classic
weapon and spawn randomness
Insurgency
No killcam or HUD hides enemy positions
Insurgency leans a little harder on optimization, though the gap is small.
Deathmatch Classic
limited map and weapon-control knowledge
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.
