head to head
StarCraft II: Wings of Liberty asks more than Warhammer 40,000: Dawn of War III, and the gap is execution.

Execution · Grand Arena
Real-time strategy where hands, reads, and build optimization all matter at the top.

Execution · Grand Arena
Elite-focused 40K RTS where power node pressure and ability-chain timing test both micro and opponent reading.
StarCraft II: Wings of Liberty leans Execution (Grand Arena); Warhammer 40,000: Dawn of War III leans Execution (Grand Arena).
StarCraft II: Wings of Liberty leans clearly harder on execution.
StarCraft II: Wings of Liberty
APM, macro, micro-control under pressure

StarCraft II: Wings of Liberty
1v1 ladder vs adaptive humans modeling you
Warhammer 40,000: Dawn of War III
Three-race elite compositions must be scouted and countered
Warhammer 40,000: Dawn of War III leans a little harder on variance, though the gap is small.
StarCraft II: Wings of Liberty
map spawns minor; mostly known
Warhammer 40,000: Dawn of War III
Power node variance and ability cooldown RNG add moderate uncertainty
StarCraft II: Wings of Liberty leans clearly harder on optimization.
StarCraft II: Wings of Liberty
build orders, economy curves heavily solved
Warhammer 40,000: Dawn of War III
Elite point allocation and doctrine selection are defined optimization problems
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.
