I think it may be because your eye "picks" the smoother shots and passes on the jarring ones? The Noctilux can misbehave (harsh, double lines, etc.) as well.
Sorry, I disagree completely. If you look closely at the shots that I "hand picked" above, you will see precisely those characteristics, but they are smoother than those painted by the Hex (and, perhaps, the Canon).
If you are just as happy – or happier – with the Hexanon, then I'm delighted for you. But to my eye, the Noctilux clearly produces the smoothest, most pleasing OOF renderings.
The Noctlilux fingerprint is unique, and my favorite of the super-fast lenses. If you prefer another, then you've saved a lot of money – congratulations.
