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 weapons-based 3D fighter where Reversal Edge decisions and ring positioning create constant human reads.

Execution · Grand Arena
A refined KOF entry that lowers the execution bar slightly while preserving the team-order reads and punish game.
SoulCalibur VI leans Execution (Grand Arena); The King of Fighters XV 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.
SoulCalibur VI
Reversal Edge timing and long lethal hit strings require tight execution
The King of Fighters XV
Shatter Strike and MAX Mode combos demand practiced precise inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
SoulCalibur VI
Reversal Edge is a pure read-off mechanic against human opponents
The King of Fighters XV
Team order choices and opponent habit exploitation remain central
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
SoulCalibur VI
No RNG; ring position is full information
The King of Fighters XV
No RNG; all information is visible in the match
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

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.
