[Xperia Z3 General] bart-videophile:
So, yeah, that's for each to decide I suppose, in how far the camera upgrade (next to perhaps some other advantages) is worth it. I would be buying it on contract and the deal with the Note 4 would mean I would have to pay about 70 euro extra for the phone, with the monthly costs staying the same. Of course I would have to look at the overall picture (regardless) but if I really feel I'd be happier with it, I wouldn't mind paying this (in my mind) relatively small extra sum. I mean, it's an expensive item to begin with, and I have to make due with it for the next two years...

I agree the Z3 is handier, size wise, looks better overall (re: design), and I much enjoy the speed/smoothness of the UI. However, if the Note 4 is noticeably better in the camera division (both when it comes to photos and videos), this all could take a backseat for me, since I especially value the video recording capabilities. So far, except for the color aberrations (which I can 'fix' using the cloudy WB-setting, I was happy with it, but I hadn't extensively tested it. Then I saw the following youtube video, which gave me great pause. The guy is filming his garden here with the Note 4 and the Z3 and, while he doesn't fully acknowledge it, the Note 4 is much better than the Z3. The Note 4 is pretty much consistently sharp and in focus, while the Z3 constantly struggles with its focus. It's quite the blurry mess, I must say. And when moving into an alley, and later an indoor area, the warps/break-ups of the image, are very off-putting. Is this is the norm, and not just due to incorrect settings or a bad/faulty device, then I'm pretty much ready to make the trade.

Still, I'm holding off judgment for now since, like I said, the videos I did record with the Z3 up until now have been quite alright (though not yet spectacular perhaps), so I'll record some more (and very diverse) scenery, once I get it back from servicing. But I surely hope it's not the same as (radicans described/showed with) photos. I.e. that the Z3 looks fine with buildings, but severely drops the ball when recording nature. Because, even though these video's won't take up the lion's share of my recordings, they do come up, and I'd like them to be at least be decently focused.

Apart from this, while the colors on the Note 4 are probably not entirely true to life (and too warm/romantic), the cold/blueish tint on the Z3 is a bit unattractive and the colors on the Note 4 much more pleasing, as far as I'm concerned.

Here is the vid I'm talking about:

(Particularly the scenes around 4:24 and 6:20)

Again, I agree it's a great package, but the camera is quite important to me, as you have gathered by now. Now if it's only marginally worse than the competition (or even much worse photo wise but on par video wise), I'd stick with it. If it's substantial, then I'm seriously considering switching phones.

As an aside, PS4 remote play is cool, but for me only when I'd be able to use it on a friend's WiFi-network (when at home, I just play on my projector). Regardless, I don't even have a PS4 yet, so now this is still a moot point ;).

What's also becoming more and more interesting to me, as far as Note-features go (having seen a couple of youtube videos on it), is its S Pen (functionality). You can do quite some amazing things with it. It would be nice to really delve into it and get the creative juices flowing. Now, it's very well possible that I won't do much with it in the end, but it looks quite promising to say the least.
