head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Competitive PvP
Large-scale modern combined-arms shooter built on destructible maps and squad teamwork.

Execution · Competitive PvP
A baseball sim testing swing timing and the pitcher-batter guessing duel atop roster strategy.
Battlefield 3 leans Execution (Competitive PvP); MLB 15: The Show 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.
Battlefield 3
Gunplay, suppression management, and vehicle piloting
MLB 15: The Show
Pitch timing and swing precision set the physical ceiling
MLB 15: The Show leans a little harder on reads, though the gap is small.
Battlefield 3
Human teams adapt routes and armor pushes
MLB 15: The Show
Guessing a human pitcher's sequence is classic mind-gaming
MLB 15: The Show leans a little harder on variance, though the gap is small.
Battlefield 3
Spawns, destruction, and vehicle drops shuffle engagements
MLB 15: The Show
Batted-ball physics and simulation rolls add real randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield 3
Unlock paths, class synergy, and map control
MLB 15: The Show
Roster building, matchups, and situational strategy run underneath
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.
