Portal leans clearly harder on execution.
Final Fantasy X
Fully turn-based; zero time pressure on inputs
Portal
Portal placement timing modest.

Final Fantasy X
All aeons and fiends operate on fixed AI scripts
Portal
No adversary modeling player.
Variance2 vs 0
Final Fantasy X leans clearly harder on variance.

Final Fantasy X
Sphere Grid routing and break damage limits make the game theoretically solvable
Portal
Pure puzzle-solving 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.
