head to head
Neither is simply harder - they are hard in different places. The Ship: Remasted demands more reads; Worms W.M.D demands more execution.

The Ship: Remasted leans Reads (Pure Mind Games); Worms W.M.D leans Reads (Competitive PvP).
Worms W.M.D leans clearly harder on execution.
The Ship: Remasted
Attacks land easily; no aim-heavy ceiling
Worms W.M.D
Shot arcs, rope swings and vehicle control demand precision
The Ship: Remasted leans clearly harder on reads.
The Ship: Remasted
Stalking and evading a human hunter who models you is everything
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.
The Ship: Remasted
Hidden quarry identity adds investigative uncertainty
Worms W.M.D
Wind, crates and random terrain reshape options
Worms W.M.D leans a little harder on optimization, though the gap is small.
The Ship: Remasted
Needs management and weapon access reward planning
Worms W.M.D
Crafting and weapon budgeting reward planned turns
