Day of the TentaclePortal 2
Axis by axis
Execution1 vs 3
Portal 2 leans clearly harder on execution.
Day of the Tentacle
SCUMM interface eliminates any timing or motor demand
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.

No opponent; multi-era puzzles are fully scripted
Portal 2
No opponent; puzzles are static.

Day of the Tentacle leans a little harder on variance, though the gap is small.
Day of the Tentacle
Deterministic world state across three time periods
Portal 2
Puzzles are deterministic with no randomness.
Optimization9 vs 9
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Day of the Tentacle
Cross-era cause-and-effect chains form a tightly solvable logic puzzle
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.
