If already vested in the Apple ecosystem, I get why the Plus is the preferred device. Why not? Good device.
That said, for a true gadget geek or a person non vested in the ecosystem, the Note 7 has things in its favor.
Better display. Even at same FHD resolution.
Better camera overall
No ITunes dependence
File drag and drop
Natively delete photos without syncing iTunes
True OTG support
More storage capability without cloud.
7% bigger display in 10% smaller footprint.
Can be used with one hand without issue. Unless smaller hands.
Integrated pen function.
Even battery life is on par if you iPhonetise' the Note 7 (set to FHD and limit background tasks).
Tons of great emulators
Tons of custom theme options
Flash support
None of the last several features above requiring jailbreak.
3.5 mm jack
Tons More codec support
Gear VR (iPhone Plus 1080p split in two for VR is not too good)
Not seeing how any gadget person not already vested in Apple not seeing the Note 7 as the better device.
This is the close to I can come to feigning incredulity
