head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Competitive PvP
A class-based shooter testing approachable aim and counter-picking against human teams.

Execution · Pure Mechanics
Grapple and reversal timing with light mindgames against human opponents.
Plants vs. Zombies: Garden Warfare leans Execution (Competitive PvP); WWF SmackDown! Just Bring It leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Plants vs. Zombies: Garden Warfare
Third-person aim and ability timing carry every fight
WWF SmackDown! Just Bring It
Grapple timing and reversal windows decide matches
Plants vs. Zombies: Garden Warfare leans a little harder on reads, though the gap is small.
Plants vs. Zombies: Garden Warfare
Human opponents flank and juke in class-based skirmishes
WWF SmackDown! Just Bring It
Human opponents invite light reversal mindgames
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Plants vs. Zombies: Garden Warfare
Sticker pack unlocks randomise progression, not matches
WWF SmackDown! Just Bring It
Weapon spawns and AI interference add small chaos
Plants vs. Zombies: Garden Warfare leans a little harder on optimization, though the gap is small.
Plants vs. Zombies: Garden Warfare
Class counters and objective timing reward team planning
WWF SmackDown! Just Bring It
Move-set knowledge and match-type tactics are quickly learned
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.
