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 · Grand Arena
A football sim testing stick execution, play-call reads, and playbook optimisation against opponents.

Execution · Competitive PvP
Class-based team shooter with deep mind games.
NFL 2K1 leans Execution (Grand Arena); 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.
NFL 2K1
Precise stick control on passes and jukes matters
Team Fortress 2
Projectile aim and rocket jumps reward hands
Team Fortress 2 leans a little harder on reads, though the gap is small.
NFL 2K1
Reading a human opponent's play-calls is central
Team Fortress 2
Spy/sniper duels are pure prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
NFL 2K1
Fumbles and catch outcomes add measured chaos
Team Fortress 2
Random crits and spread inject RNG
NFL 2K1 leans a little harder on optimization, though the gap is small.
NFL 2K1
Playbook knowledge and matchup exploitation reward study
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.
