The HTC U11 and the Meizu Note 6 both feature the same main Sensor, rated all time best Sensor of any Cellphone by DxOMark. The Samsung Note 8 OIS is excellent. New Phones are coming with 3x to 5x Optical Zoom and Optical Image Stabilization using the Hawkeye from Corephotonics.
By February the SnapDragon 845, correct Sensor orientation, and Optical Zoom will all be available; phones purchased in the months to come will be behind in two or more features.
The orientation of the Samsung Note 8 (and even the LG V30) Cameras in Landscape Mode is incorrect for 3D/AR/VR and use with Goggles, if you want to have depth perception.
Notice how the Meizu Note 6 and the iPhone 8 have their Sensors oriented correctly for depth perception in Landscape Mode.
Imo even without the extra camera features , the note 8 had the value in the bag just with the S pen alone .
The other extras on the note are just gravy .
also the open dual app function is a highly desirable feature .
@Robic The orientation of the different lenses does not matter. Simple test: Lay down on a bed & compare the image of the vertical eye layout. Then even close one eye & see the difference. The brain does the most of the work.
The Note 8 brain/lenses/sensors are very capable to get 100/100 mark for Zoom Camera on DxOMark.
Unlike our eyes, the 2 lenses are different & can provide depth info (x2 optical zoom with OIS):
Primary 12MP 1/2.55” sensor with 26mm (Wide-angle) f/1.7 lens (1.4um pixel size)
Secondary 12MP 1/3.6” sensor with 52mm (Telephoto) f/2.4 lens (1.0um pixel size)
Btw. Retina display is a marketing gimmick. Now you know where the confusion comes from.
