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 · Practiced Mastery
A looter-shooter loop testing build optimisation more than the shooting itself.

Optimization · Practiced Mastery
An open-world action game where hacking the city's infrastructure is your main weapon.
Suicide Squad: Kill the Justice League leans Optimization (Practiced Mastery); Watch Dogs leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Suicide Squad: Kill the Justice League
Traversal-shooting needs moderate aim, generous by shooter standards
Watch Dogs
Cover shooting and driving at modest difficulty
Watch Dogs leans a little harder on reads, though the gap is small.
Suicide Squad: Kill the Justice League
Brainwashed bosses are scripted encounters
Watch Dogs
Online invasions add a small human element
Suicide Squad: Kill the Justice League leans a little harder on variance, though the gap is small.
Suicide Squad: Kill the Justice League
Loot rolls gate the live-service grind
Watch Dogs
Guard placements are knowable on approach
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Suicide Squad: Kill the Justice League
Gear builds and mission farming dominate endgame
Watch Dogs
Hacking chains and camera routes make stealth 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.
