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.

Execution · Practiced Mastery
NES boxing game built entirely on memorizing opponent tells and executing split-second counters.

Execution · Practiced Mastery
Combo execution layered over solving each park's optimal scoring line.
Mike Tyson's Punch-Out!! leans Execution (Practiced Mastery); Tony Hawk's Underground 2 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.
Mike Tyson's Punch-Out!!
Frame-tight dodges and counters, brutal at Tyson
Tony Hawk's Underground 2
Combo timing, balance meters and manuals demand practiced hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mike Tyson's Punch-Out!!
Every boxer follows fixed tells and patterns
Tony Hawk's Underground 2
No opponent adapts; score attack is solo
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mike Tyson's Punch-Out!!
Almost fully deterministic once patterns are known
Tony Hawk's Underground 2
Maps and goals are fixed and fully knowable
Mike Tyson's Punch-Out!! leans a little harder on optimization, though the gap is small.
Mike Tyson's Punch-Out!!
Memorizing each opponent's pattern is half the game
Tony Hawk's Underground 2
Finding the highest-scoring line through each park is solvable
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.
