I'm also between the iPhone 6+ and the Note 4. This is what I posted in another Note 4 vs iPhone 6+ thread...
Meh...
Camera too soon to tell, OIS on both of them. I liked my camera on the 5s better than the Note 3 so I think Apple may win, but who knows.
build quality: Note 3 has as good of build quality as the 5s IMO. Looking at those janky antenna lines on the ip6+ and I'll bet the Note 4 has a better build. All metal back is a large negative IMO, requires a case not to scratch or dent it, less grip, and you can't remove the back to replace the battery or access a micro SD card, which the iPhone doesn't have anyway. Big points to the Note 4 there.
Screen versus battery: Dunno, might be valid depending on battery time. Has Samsung released battery times? Apple says what 12 hours wifi browsing I think? I'll bet it's pretty even though even with the higher resolution, my Note 3 is a freakin monster when it comes to battery life.
Touchwiz lag, IMO complete and utter BS nonsense. I don't have any lag on my Note 3. Better experience is subjective, but I do tend to agree that iOS is just a bit simpler in many aspects, but it's not like it's rocket science to learn Android either.
No comparsion on features IMO. S-pen, multi windows, micro SD card etc just trounce what the ip6+ has to offer. Plus I think the aesthetics are much nicer on the N4, much smaller bezels, the backing looks and feels nicer IMO. The only thing I fear is that the fingerprint sensor will suck on the N4 like the S5, I really miss the FP sensor on the iPhone which was virtually perfect.
