head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
Memorising scripted boxer patterns and executing split-second counters.

Execution · Practiced Mastery
A one-hit boss-rush where solving each titan still demands perfect execution.
Super Punch-Out!! leans Execution (Practiced Mastery); Titan Souls leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Super Punch-Out!!
Frame-tight dodges and counters decide every bout
Titan Souls
One arrow, one hit point; every shot must be perfect
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Super Punch-Out!!
Opponents are scripted pattern puzzles, not adapting minds
Titan Souls
Bosses are scripted patterns, not adaptive minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Super Punch-Out!!
Patterns are fixed once learned - nothing random
Titan Souls
Unknown boss gimmicks only on first attempts
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Super Punch-Out!!
Memorising each boxer's tells and optimal counters is the game
Titan Souls
Each titan has a solvable weak-point strategy
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.
