head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Competitive PvP
Supercell's snappy top-down team brawler built around three-minute objective fights.

Execution · Competitive PvP
Artillery aim and turn planning against humans under wind and crate randomness.
Brawl Stars leans Execution (Competitive PvP); Worms Reloaded leans Execution (Competitive PvP).
Brawl Stars leans a little harder on execution, though the gap is small.
Brawl Stars
Aim, dodging, and ability timing in real time
Worms Reloaded
Grenade arcs and ninja-rope shots demand fine aim control
Brawl Stars leans a little harder on reads, though the gap is small.
Brawl Stars
Human teams rotate, bait supers, and adapt
Worms Reloaded
Anticipating human opponents' target priorities shifts each turn
Worms Reloaded leans a little harder on variance, though the gap is small.
Brawl Stars
Bush ambushes and power-cube spawns hide information
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.
Brawl Stars
Brawler matchups and map strategy are learnable
Worms Reloaded
Weapon economy and positioning theory reward planning
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.
