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

NBA Jam Tournament Edition
Turbo timing, steals and shot releases reward fast hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield Vietnam
Human squads flank and contest objectives unpredictably
NBA Jam Tournament Edition
Head-to-head play is constant guessing of the other player
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
