I have a Nokia 1020, and I've been taking pictures with iPhones for years now, and while the camera is absolutely incredible and I think the overall quality and detail beats the iPhone, the 1020 has 3 main problems: (1) consistency. (2) speed. (3) color accuracy. All these problems are actually co-related with each other.
The picture is proof that the Nokia 1020 has trouble taking good photos constantly. If you look at
PUREVIEW PHOTOGRAPHY - HOME you can see some truly fantastic pictures taken with the 1020 in low light and they do look better than what the iPhone can do; it's a pure hardware advantage. And I've personally taken some photos in the dark and they've impressed me that a phone can do this. However, like the photo you have and some photos I have, the 1020 could sometimes have trouble to focus and bring all the light it could, and then turns images into utter sumdgy crap. But trust me, the Nokia 1020 could do much better than what this picture shows, and it can do better than what the iPhone does.
Speed of course is the biggest issue with the 1020. The Snapdragon dual-core processor just cannot handle taking 41-megapixel shots fast. Opening the camera takes long, saving the photo takes even longer, so the speed between shots is super slow, and it's nearly impossible to take action shots of a kid or a pet playing. You can resort to the "action shot" mode, but that only takes 5-megapixel photos and lowers the quality by a lot. WindowsPhone 8.1 made a bit better, but still way too slow. The iPhone easily takes better photos in action, while the Nokia has better quality in taking landscape or stationary photos.
I also face a few problems with color accuracy sometimes. Again, the 1020 photos aren't consistent, so sometimes you get photos with brilliant colors, and other times you get pinkish whites and overly-saturated red. But of course, with color, there's nothing that cannot be fixed with few editing.
As comparing the 1020 and the iPhone, I've been a huge fan of iPhone photography for years now, and Flickr and Instagram on iOS are decades better than what WindowsPhone offers, and actually, I send my 1020 photos to my iPhone to upload to Instagram, because Instagram on WP degrades the quality A LOT. And there are editing apps on iOS that WP will never dream of having. The iPhone is a better phone camera in terms of taking quick shots of something you saw on the street, or taking a slow-mo video, but the hardware of the 1020 is better, and you can get better results. The 1020 is mostly suited for landscapes, or portraits of people, as you can zoom in and not lose any quality. The 1020 is also capable of RAW images, which is huge. Video is almost the same, but the 1020 has better sound to my ears and has options to record audio at 100Hz or 200Hz, which is pretty impressive again.
But when people complain about the camera protrusion on the iPhone 6 and 6 Plus, I tell them "just see the Oreo biscuit that's sticking out of my 1020"
