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
Methodical infiltration planning paid off by one well-compensated rifle shot.

Execution · Practiced Mastery
Timing-based wuxia combat layered over build optimisation in an open world.
Sniper Elite: Resistance leans Execution (Practiced Mastery); Where Winds Meet 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.
Sniper Elite: Resistance
Ballistics-compensated shots and stealth timing need steady hands
Where Winds Meet
Parry and dodge timing in martial-arts duels rewards hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sniper Elite: Resistance
Invasion mode adds occasional human cat-and-mouse
Where Winds Meet
PvP modes add some human prediction, mostly PvE scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sniper Elite: Resistance
Patrol details are scripted-but-unknown on first infiltration
Where Winds Meet
Open-world events and drops add mild randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Sniper Elite: Resistance
Route planning, sound masking and shot setups reward study
Where Winds Meet
Build crafting and boss moveset learning drive progression
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.
