Insurgency: Sandstorm
Holding angles and pushes are mind games
SoulCalibur III
Versus humans, conditioning and throw-mixup guessing decides rounds
Insurgency: Sandstorm leans a little harder on variance, though the gap is small.
Insurgency: Sandstorm
Very low RNG, near pure skill
SoulCalibur III
Deterministic combat with nothing hidden

Insurgency: Sandstorm
Loadout points and class roles tuned
SoulCalibur III
Frame data, matchup study and stage knowledge run deep
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.
