The aesthetics are in the mind of the beholder, much as is Louis XIV furniture and Jackson Pollock. I would say unless you are made of $$, no it's not worth it.
Early buyers had no choice, but the other options work as well, as it is just a lens hood. But if you a person with a yen for a Crocodile skin Leica M:
then that is the free market at work!
I have two hoods, one the cheap knockoff, not the pricey knockoff; and for times when I want the camera to be shorter, I use a 49mm to 37mm step down ring, works on top of a filter without vignetting - well, no more than the lens manages in unadorned trim anyway. Even got myself a Schneider Kreuznach push on lens cap as I don't like the dust gathering pinch ones. How's that for aesthetics? lol, we are all crazy in our own way...
