head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Competitive PvP
Artillery touch, human prediction and weapon economy in destructible 3D terrain.

Execution · Competitive PvP
Artillery aim and turn planning against humans under wind and crate randomness.
Worms 3D leans Execution (Competitive PvP); Worms Reloaded 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.
Worms 3D
Judging grenade arcs and wind in 3D takes real touch
Worms Reloaded
Grenade arcs and ninja-rope shots demand fine aim control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Worms 3D
Predicting where a human hides and strikes next matters
Worms Reloaded
Anticipating human opponents' target priorities shifts each turn
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Worms 3D
Wind, crate drops and terrain chaos swing turns
Worms Reloaded
Random terrain, crates and wind perturb every shot
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Worms 3D
Weapon economy and positioning math reward planning
Worms Reloaded
Weapon economy and positioning theory reward planning
