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

Execution · Grand Arena
A SNK classic where Just Defend forces constant read-off decisions and T.O.P. activation rewards deep optimisation.

Execution · Grand Arena
A combo system built on constant Combo Breaker mind-games that create a unique adaptive read-off at every moment of a combo.
Garou: Mark of the Wolves leans Execution (Grand Arena); Killer Instinct (2013) leans Execution (Grand Arena).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Garou: Mark of the Wolves
Just Defend timing and T.O.P. combo precision demand high execution
Killer Instinct (2013)
Shadow counters and Combo Breaker timing demand very precise inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Garou: Mark of the Wolves
Just Defend is a pure read mechanic against an adaptive opponent
Killer Instinct (2013)
Combo Breaker prediction is a pure read-off against an adaptive opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Garou: Mark of the Wolves
No RNG; all match states are visible
Killer Instinct (2013)
No RNG; all mechanics are fully visible
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Garou: Mark of the Wolves
T.O.P. activation timing and matchup frame data are well-studied
Killer Instinct (2013)
Instinct activation timing and optimal opener routes are well-studied
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.
