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 · Practiced Mastery
A retro gridiron sim mixing input timing with play-call guessing against an opponent.

Execution · Competitive PvP
Football stick execution and opponent reading, salted with bounce-of-the-ball luck.
ABC Monday Night Football leans Execution (Practiced Mastery); FIFA Soccer 07 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.
ABC Monday Night Football
Timing passes, jukes and tackles demands controller precision
FIFA Soccer 07
Stick skills and timing on passes and finishing
FIFA Soccer 07 leans a little harder on reads, though the gap is small.
ABC Monday Night Football
Two-player matches involve guessing the human's play call
FIFA Soccer 07
Versus humans, baiting tackles and disguising attacks matters
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
ABC Monday Night Football
Fumble and catch rolls add bounded football randomness
FIFA Soccer 07
Deflections and keeper randomness swing single matches
ABC Monday Night Football leans a little harder on optimization, though the gap is small.
ABC Monday Night Football
Play-calling and roster knowledge form a solvable layer
FIFA Soccer 07
Formations and exploit patterns are learnable meta
