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
Boxing sim where matches hinge on timing, feints, and counter-punching.

Reads · Competitive PvP
Minimalist fencing duel that is almost entirely about out-guessing one human.
Fight Night Champion leans Execution (Competitive PvP); Nidhogg leans Reads (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Fight Night Champion
Punch timing, counters, and stick precision
Nidhogg
Sword-height changes and dive-kicks need quick hands
Nidhogg leans a little harder on reads, though the gap is small.
Fight Night Champion
Boxing humans is feint-and-counter prediction
Nidhogg
Pure human duels of feints and conditioning
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fight Night Champion
Little hidden information in the ring
Nidhogg
Symmetric deterministic arenas
Fight Night Champion leans a little harder on optimization, though the gap is small.
Fight Night Champion
Stamina management and fighter build choices
Nidhogg
Small toolkit, little to solve beyond fundamentals
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.
