head to head
Neither is simply harder - they are hard in different places. Portal demands more optimization; Unitied demands more variance.

Portal
Portal placement timing modest.
Unitied
light tactical unit-control demands

Portal
No adversary modeling player.
Unitied
AI/PvP opponents show limited adaptivity

Deterministic chambers; no randomness.
Unitied
randomized match/event elements
Portal leans clearly harder on optimization.

Pure puzzle-solving optimization.
Unitied
team-building and tactical optimization
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.
