PortalvsQuantum Conundrum
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.
Portal
Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Quantum Conundrum
Optimization · Pure Optimization
First-person puzzle platformer about flipping physics dimensions mid-jump.
Portal leans Optimization (Pure Optimization); Quantum Conundrum leans Optimization (Pure Optimization).
PortalQuantum Conundrum
Axis by axis
Execution4 vs 4
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Portal
Portal placement timing modest.
Quantum Conundrum
Mid-air dimension-swap platforming demands real timing
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Portal
No adversary modeling player.
Quantum Conundrum
No opponent present
Variance0 vs 0
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Optimization8 vs 7
Portal leans a little harder on optimization, though the gap is small.
Portal
Pure puzzle-solving optimization.
Quantum Conundrum
Dimension-switch sequences are the solvable core
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.
