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

Optimization · Pure Optimization
An MMO solved through efficiency routing with niche tick-execution skill ceilings.

Optimization · Pure Optimization
A cover-based looter shooter where the spreadsheet of gear builds outweighs the gunplay.
Old School RuneScape leans Optimization (Pure Optimization); Tom Clancy's The Division leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Old School RuneScape
Tick-perfect inputs in high-end PvM
Tom Clancy's The Division
Cover shooting matters but bullet-sponge TTK softens aim skill
Tom Clancy's The Division leans a little harder on reads, though the gap is small.
Old School RuneScape
PvP wilderness has genuine read element
Tom Clancy's The Division
Dark Zone PvP adds real human betrayal and prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Old School RuneScape
Drop rates and clue RNG drive economy
Tom Clancy's The Division
Loot rolls gate power; drops are dice
Old School RuneScape leans a little harder on optimization, though the gap is small.
Old School RuneScape
Efficiency, routing, and GP/hour fully theorycrafted
Tom Clancy's The Division
Gear builds, talents, and DPS math dominate endgame
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.
