head to head
StarCraft II: Wings of Liberty asks more than Squad, and the gap is optimization.

Execution · Competitive PvP
Milsim 50v50 team-tactical shooter.

Execution · Grand Arena
Real-time strategy where hands, reads, and build optimization all matter at the top.
Squad leans Execution (Competitive PvP); StarCraft II: Wings of Liberty leans Execution (Grand Arena).
StarCraft II: Wings of Liberty leans a little harder on execution, though the gap is small.
Squad
Bullet drop, sway, suppression test aim
StarCraft II: Wings of Liberty
APM, macro, micro-control under pressure
StarCraft II: Wings of Liberty leans a little harder on reads, though the gap is small.
Squad
Squad tactics versus humans demand prediction
StarCraft II: Wings of Liberty
1v1 ladder vs adaptive humans modeling you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Squad
Minimal RNG, comm-driven outcomes
StarCraft II: Wings of Liberty
map spawns minor; mostly known
StarCraft II: Wings of Liberty leans clearly harder on optimization.
Squad
Logistics, FOB placement, kit choice deep
StarCraft II: Wings of Liberty
build orders, economy curves heavily solved
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.
