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
Artillery touch, human prediction and weapon economy in destructible 3D terrain.

Reads · Competitive PvP
Modern Worms with crafting and vehicles, keeping the classic turn-based destructible-terrain warfare.
Worms 3D leans Execution (Competitive PvP); Worms W.M.D leans Reads (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 W.M.D
Shot arcs, rope swings and vehicle control demand precision
Worms W.M.D leans a little harder on reads, though the gap is small.
Worms 3D
Predicting where a human hides and strikes next matters
Worms W.M.D
Multiplayer turns hinge on out-guessing rival worm placement
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 W.M.D
Wind, crates and random terrain reshape options
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 W.M.D
Crafting and weapon budgeting reward planned turns
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.
