Hexane behaves the same as butane in extraction as in it only reacts with the thc. It's something to do with polarity.
Simpson oil requires other extracts that hexane and butane leave behind.
Isoprophyl is better, it reacts with the veggie stuff that's needed in the Simpson recipe.
Butane, Hexane, and the light Naphtha extraction that Rick Simpson demonstrates on his video, are a non polar extraction with a solvent that doesn't pick up water soluble non active ingredients like chlorophyll, etc. Rick Simpson actually touts the effectiveness of his non polar naphtha extractions and Naphtha is just Pentane and Hexane. Pentane is the simple 5 carbon chain Alkane that falls between Butanes four carbon chain and Hexanes six.
His 3 minute isopropyl and ethanol extraction are a polar solvent that does pick up water solubles. I have never heard him say that they were more effective, only that he was showing those methods because they all worked and almost anyone could do them.
The heat RS uses, is a rice cooker for cooking off the solvent. As a side effect, that would also decarboxylate the oil and make it orally active.
From my perspective, the fish trap exists because of the fish, and if you get the fish, the design of the fish trap is not of prime importance. If the fish is the cannabinoids, they are relatively non-polar, so Hexane works well.
If you think alcohol does a better job of extracting, I suggest that you dissolve cannabis essential oil in alcohol and then mix that with equal parts of water and Hexane and shake.
Let that stand for awhile and check back later and note which solvent ended up with the cannabinoids.
