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
A baseball sim testing swing timing and the pitcher-batter guessing duel atop roster strategy.

Execution · Competitive PvP
Class-based team shooter with deep mind games.
MLB 15: The Show leans Execution (Competitive PvP); Team Fortress 2 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.
MLB 15: The Show
Pitch timing and swing precision set the physical ceiling
Team Fortress 2
Projectile aim and rocket jumps reward hands
Team Fortress 2 leans a little harder on reads, though the gap is small.
MLB 15: The Show
Guessing a human pitcher's sequence is classic mind-gaming
Team Fortress 2
Spy/sniper duels are pure prediction
MLB 15: The Show leans a little harder on variance, though the gap is small.
MLB 15: The Show
Batted-ball physics and simulation rolls add real randomness
Team Fortress 2
Random crits and spread inject RNG
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
MLB 15: The Show
Roster building, matchups, and situational strategy run underneath
Team Fortress 2
Class loadouts and map routes solvable
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.
