Neither is simply harder - they are hard in different places. Back to the Future: The Game demands more variance; Portal 2 demands more execution.
Back to the Future: The Game
Optimization · Pure Optimization
A story-first adventure with gentle item-puzzle logic as its only test.
Portal 2
Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.

Back to the Future: The GamePortal 2
Axis by axis
Execution0 vs 3
Portal 2 leans clearly harder on execution.
Back to the Future: The Game
Telltale point-and-click, zero dexterity
Portal 2
Portal placement requires some precision but timing is lenient.
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Back to the Future: The Game
Characters follow the episodic script
Portal 2
No opponent; puzzles are static.
Variance2 vs 0
Back to the Future: The Game leans clearly harder on variance.
Back to the Future: The Game
Puzzle solutions are hidden until found
Portal 2
Puzzles are deterministic with no randomness.
Optimization6 vs 9
Portal 2 leans clearly harder on optimization.
Back to the Future: The Game
Light item-logic puzzles drive each episode
Portal 2
Solving the puzzle's logic IS the entire game.
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.
