head to head
Neither is simply harder - they are hard in different places. Detroit: Become Human demands more optimization; VRChat demands more reads.

Optimization · Light / Casual
A branching story that tests choice exploration more than any skill.

Reads · Light / Casual
A social platform that tests presence and people skills, not gameplay mastery.
Detroit: Become Human leans Optimization (Light / Casual); VRChat leans Reads (Light / Casual).
Detroit: Become Human leans a little harder on execution, though the gap is small.
Detroit: Become Human
Quick-time events demand only basic reaction timing
VRChat
Socialising and exploring demand no mechanical skill
VRChat leans clearly harder on reads.
Detroit: Become Human
Branching script, no adaptive adversary
VRChat
Reading other humans socially, not competitively
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Detroit: Become Human
Branch consequences are hidden information until explored
VRChat
User-generated worlds surprise but aren't a skill test
Detroit: Become Human leans clearly harder on optimization.
Detroit: Become Human
Flowchart completion is a light solvable puzzle
VRChat
No win condition to optimise toward
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.
