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
Tests shot timing and faking out human defenders amid item-driven chaos.

An American football sim mixing stick execution with play-calling mind games versus opponents.
Mario Strikers Charged leans Execution (Competitive PvP); NFL 2K3 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.
Mario Strikers Charged
Timing tackles, charged shots and goalie deflections needs quick hands
NFL 2K3
Stick control of players demands timing and reaction
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Strikers Charged

NFL 2K3
Play-calling against human opponents is constant prediction
Mario Strikers Charged leans a little harder on variance, though the gap is small.
Mario Strikers Charged
Items and stage hazards inject swingy chaos into matches
NFL 2K3

Captain abilities and team builds reward knowing the systems
