Oh, boy. And Apple copied Digione:

(And the Android crowd will tell you how iOS ripped off notifications, multitasking, predictive keyboard, widgets (still poor implementation) and so on.)
The bottom line is, the S6 is still a premium product and a much better one than the Galaxies of old.
It doesn't mean that the iPhone may not have ultimately better design, or even better fit and finish. But to be fair, many pundits too an issue wit the iPhone's plastic inlays and can argue that these are almost as bad as alignment issues (which should really make Samsung embarrassed).
But keep it in perspective. When most users slap some ugly case on their iPhone, the perfect alignment is a mute point.
But Samsung has delivered a better camera, with OIS, for less money. I like that.
My point was, the S6 is a really good product. It's silly to argue that it's not.
