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
Free-to-play hero shooter where loadout cards customize champions in objective team fights.

Execution · Competitive PvP
A class-based shooter spin-off of the tower-defense series with PvP and co-op modes.
Paladins leans Execution (Competitive PvP); Plants vs. Zombies: Battle for Neighborville leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Paladins
Hitscan aim and ability timing in firefights
Plants vs. Zombies: Battle for Neighborville
aim and movement in class-based shooter combat
Paladins leans a little harder on reads, though the gap is small.
Paladins
Human teams flank, bait ults, and adapt
Plants vs. Zombies: Battle for Neighborville
predicting human opponents' pushes and flanks
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Paladins
Card draft order adds mild run variance
Plants vs. Zombies: Battle for Neighborville
minor loot and spawn randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Paladins
Loadout card builds and item counter-buying
Plants vs. Zombies: Battle for Neighborville
class builds and lane strategy are solvable
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.
