Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Agents of Mayhem
Triple-jump shooting demands moderate aim and movement
Watch Dogs
Cover shooting and driving at modest difficulty
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Agents of Mayhem
LEGION troops follow predictable scripts
Watch Dogs
Online invasions add a small human element
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Agents of Mayhem
Procedural lair layouts add mild uncertainty
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.
Agents of Mayhem
Agent-swap squad composition and gadget builds reward theorycrafting
Watch Dogs
Hacking chains and camera routes make stealth solvable
