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 · Practiced Mastery
Galaxy-spanning space sim about flight and trade.

Optimization · Pure Optimization
A slower, more deliberate MMORPG where optimal preparation and class knowledge define performance.
Elite Dangerous leans Optimization (Practiced Mastery); WoW Classic leans Optimization (Pure Optimization).
Elite Dangerous leans a little harder on execution, though the gap is small.
Elite Dangerous
Flight controls, docking, combat aim
WoW Classic
Slower combat reduces twitch ceiling versus retail
WoW Classic leans a little harder on reads, though the gap is small.
Elite Dangerous
Light PvP reads, mostly PvE
WoW Classic
World PvP and battlegrounds involve real human prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Elite Dangerous
Procedural galaxy, mission variance
WoW Classic
Resist RNG and gear drops add meaningful hidden randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Elite Dangerous
Ship build, trade routes, engineering grind
WoW Classic
Class specs, consumable lists, and dungeon routes are deeply 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.
