The note 4 is way better than the note 3 on signal strength. The nexus 6 is at least as good as the note 4. I sit in my house in a weird near-deadzone, and both the note 4 and n6 can hold a steady signal. The note 3 would lose signal occasionally.
My only negative for the n6 is the camera. It's not "nearly as good" as the note 4 as people have repeatedly claimed on this forum. I've been doing dozens of side-by-sides with both phones in various lighting for the last 2 days with my toddle and dogs and the n6 isn't even in the same ballpark at the note 4. There are details that are crystal clear on the note 4 pictures when you zoom in a little bit that are just blurry smudges on the n6.
Can the n6 take pictures that (uncropped) can happily go up on facebook? Yes. Is it anywhere near as good at the note 4? Not even close.
Of all the side-by-sides this is probably the one where the nexus 6 is closest to the note 4. See if you can guess which is the nexus and which is the note.
(hdr off for both, max rez for both, slight resizing to get the photos the same size, taken at the same time while i held both cameras with the focus on the dog's head, no post-processing)
Unfortunately for my decision of which to keep the nexus 6 is a way better experience in every other way than the note 4. Its smoother, app switching is great, the speakers are fantastic, and the benefits of the faster updates.
