I think its the fastest/highest resolution phone available at the moment?
Certainly it has the largest screen, but that does not automatically grant it the "best" title. Some would even consider the size a negative.
Its lack of NFC and a notification LED are among its draw backs. The s-pen is awesome and the fact that its optional makes it only a positive.
In the end it all comes down to preference. That said, it would certainly get my vote for best phone ever.
