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
A licensed brawler testing combat timing and memorised boss patterns.

Execution · Practiced Mastery
Sequel that trims the open world and doubles down on stylish assassin duels.
Dragon Ball: Revenge of King Piccolo leans Execution (Practiced Mastery); No More Heroes 2: Desperate Struggle 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.
Dragon Ball: Revenge of King Piccolo
Combo timing and platforming reflexes carry the levels
No More Heroes 2: Desperate Struggle
Faster boss duels with dodge timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball: Revenge of King Piccolo
Bosses run scripted patterns, never adapt
No More Heroes 2: Desperate Struggle
Scripted assassin patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball: Revenge of King Piccolo
Level content is fixed after one playthrough
No More Heroes 2: Desperate Struggle
Fixed fights, retro minigames
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball: Revenge of King Piccolo
Learning boss movesets and stage routes is the rest
No More Heroes 2: Desperate Struggle
Pattern study and ability upgrades
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.
