Left to right. Gold S6 Edge, LG G4 and Honor 6+. All on max brightness.

I also noticed the Honor 6+ has no logo on the front.

Profile photos.

The S6 Edge is smaller than the others.

But side view reveals you could tuck the S6 Edge under the curve of the G4.

Despite the Honor 6+ being made of plastic from the front it looks better than the G4.

The leather backed G4 has the best rear of the three.
