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.

Optimization · Grand Arena
Modern AoE balances macro hands with adaptive multiplayer.

Reads · Grand Arena
A team MOBA where map control and adaptive duels decide objectives.
Age of Empires IV leans Optimization (Grand Arena); League of Legends leans Reads (Grand Arena).
Age of Empires IV leans a little harder on execution, though the gap is small.
Age of Empires IV
APM and micro matter, lower than SC2
League of Legends
Mechanics matter but not aimbot-decisive.
League of Legends leans a little harder on reads, though the gap is small.
Age of Empires IV
1v1 ladder vs adapting humans
League of Legends
Lane and jungle constantly mind-game opponents.
League of Legends leans a little harder on variance, though the gap is small.
Age of Empires IV
map gen minor
League of Legends
Champion select and minor RNG only.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Age of Empires IV
civ build orders well solved
League of Legends
Itemization, wave management, and macro are solvable.
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.
