Too big. The 6 Plus feels surprisingly good in the hand and I can actually reach everything on the screen. The Note 4 is just too wide. Even the G3 is pushing it. I would never be able to grip the N6. And there is still the issue of the camera. Moto just can't get that right.
G3 is less narrow than 6+..and you can use LMT pie controls...
