I own both phones. I go between them every week. There are times when I switch after a couple of days. They're both great phones. I couldn't imagine not having either phone.
The N6 is big and there are times I don't want to carry. Having said that, I love stock Android. The phone is really smooth from every aspect. I've done numerous comparisons with similar wallpapers and the N4 has a slight edge. This doesn't mean the N6 is bad, but you can see a slight advantage when side by side. The curve on the back actually feels better tin the hand than the square N4. With that said, the N4 is lighter and feels better in the pocket.
From a camera perspective, it is really hard to determine which is better. I truly think it is subjective. The N4s pictures are sharper but I don't know if that is always a good thing. The N6 pics are not soft- just not as sharp as the N4. I don't like taking pictures with any phone in low light, so I have no opinion. The N4 excels in providing options on taking pictures without doing hand gymnastics. In my opinion, this is where Touchwiz shines. Having the ability to say cheese and a picture is taken is worth the price of admission. Also, you have the option of using the heart rate sensor to take pictures as well.
As for battery life, this is a push for me. I'm a heavy media consumer and use all of my phones similarly. I don't conduct tests to see how long I can go before recharging. I have a spare battery for my N4 and a portable battery pack for the N6. If I'm at my job or home office, I plug in between 30-60%. There is just no reason for me not to have a charged phone. Lastly, I charge my phones at night. There is never a time when I feel I'm in danger of not having enough juice for any reason. When I hear folks say the phone doesn't last more than 24 hours, I wonder what do you truly expect from a device using so much data among other things. Why not just charge the phone overnight? It is something I'll never understand. It is also something I don't forget as it is right on my night stand. In any event, I think the majority of people can easily get through an 8 hour work day with these phones.
You just can't go wrong with either phone. You already know both phones are big, so your reason(s) not to keep should be for other reasons. I can understand how folks can pick either phone. I've decided to keep both and have the best of both worlds.
