I could do the same coin shot with a standard Canon 28-135 lens and tube not using an additional expensive close up lens. Mind you the flower is unshap all over whereas the other photo of coins with a "kit lens" is incredibly sharp.
So the point would be ?
As for the picture comparison sorry, must be too technical for me! If that is supposed to be a parallel between close up lens or not, it is as off beat as a bike taking you as many places as acer, but cheaper. A pointless argument as each have their merits.
and as for this "Try laying on your hand till its numb....Feels like someone else's then....Still no substitute for the real thing..... Duh! sorry.
