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
N64 spy FPS famed for gadget-heavy missions and bot-filled multiplayer.

Execution · Competitive PvP
A class-based shooter testing approachable aim and counter-picking against human teams.
Perfect Dark leans Execution (Practiced Mastery); Plants vs. Zombies: Garden Warfare leans Execution (Competitive PvP).
Perfect Dark leans a little harder on execution, though the gap is small.
Perfect Dark
N64 manual aim and tight mission play
Plants vs. Zombies: Garden Warfare
Third-person aim and ability timing carry every fight
Plants vs. Zombies: Garden Warfare leans a little harder on reads, though the gap is small.
Perfect Dark
Multiplayer and clever sims add some human-style adaptation
Plants vs. Zombies: Garden Warfare
Human opponents flank and juke in class-based skirmishes
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Perfect Dark
Mission scripting fixed once learned
Plants vs. Zombies: Garden Warfare
Sticker pack unlocks randomise progression, not matches
Perfect Dark leans a little harder on optimization, though the gap is small.
Perfect Dark
Objective routing on harder difficulty tiers
Plants vs. Zombies: Garden Warfare
Class counters and objective timing reward team planning
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.
