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

Execution · Practiced Mastery
Arcade boss-rush testing pattern execution and weakness-order knowledge.

Execution · Practiced Mastery
NES boxing game built entirely on memorizing opponent tells and executing split-second counters.
Mega Man: The Power Battle leans Execution (Practiced Mastery); Mike Tyson's Punch-Out!! leans Execution (Practiced Mastery).
Mike Tyson's Punch-Out!! leans a little harder on execution, though the gap is small.
Mega Man: The Power Battle
Boss pattern dodging at arcade pace tests the hands
Mike Tyson's Punch-Out!!
Frame-tight dodges and counters, brutal at Tyson
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man: The Power Battle
Robot Masters cycle fixed movesets
Mike Tyson's Punch-Out!!
Every boxer follows fixed tells and patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man: The Power Battle
Boss selection order barely changes the run
Mike Tyson's Punch-Out!!
Almost fully deterministic once patterns are known
Mike Tyson's Punch-Out!! leans a little harder on optimization, though the gap is small.
Mega Man: The Power Battle
Weapon-weakness ordering is a solvable puzzle
Mike Tyson's Punch-Out!!
Memorizing each opponent's pattern is half the game
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.
