head to head
Neither is simply harder - they are hard in different places. PUBG Mobile demands more execution; World of Tanks demands more optimization.

Execution · Grand Arena
Battle royale survival blending aim, rotation planning, and heavy circle-and-loot RNG.

Reads · Mind & Math
Slow-burn tank PvP with deep meta.
PUBG Mobile leans Execution (Grand Arena); World of Tanks leans Reads (Mind & Math).
PUBG Mobile leans clearly harder on execution.
PUBG Mobile
Touchscreen aim and recoil control set the ceiling
World of Tanks
Aim and lead matter but slow
World of Tanks leans a little harder on reads, though the gap is small.
PUBG Mobile
Outguessing rotations and third-party timing of human squads
World of Tanks
Map positioning versus humans is reads
PUBG Mobile leans clearly harder on variance.
PUBG Mobile
Circle placement, loot and drop locations dominate single matches
World of Tanks
Shell RNG and matchmaking swing fights
World of Tanks leans clearly harder on optimization.
PUBG Mobile
Zone rotation theory and loadout priorities are well mapped
World of Tanks
Tank loadouts and crew skills 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.
