About the same time in December when I bought my iPhone X Plus, I also spent $1k on a Sony RX100 V (version 5) point and shoot camera, which has a larger Sony sensor and about a thousand settings as well as a super auto setting. Both are smaller and more convenient to use than my 50x digital zoom 2013 Sony Cybershot DSC-HX300, which has a 1200m telescoping lens that is great for hikers who don't want to carry a lens bag.
The RX 100 takes better pictures on Super Auto than the iPhone, but it's less convenient when it comes to putting the pictures on the phone and on iCloud. It's easier to email iPhone pictures right away than to mess with the other two cameras, which I have to connect to a computer to transfer pictures (easier than using the RX100's wifi feature, which is clunky.).
Basically, the iPhone is a Sony camera set to Super iAuto. What I like about it most of the time is that its big screen gives you a better look at your newest pictures. It lets you zoom in and out, and it adjusts for the light pretty well. Also, in bright sunlight, I can see what I'm shooting on the iPhone a lot better than on the RX-100. Indeed, in really bright light, I can't see what I'm shooting with the latter camera even when I take off my sunglasses.
The RX100 is a better wide angle camera, and it is much better in rooms with poor light. Further, you can manually set the aperture and shutter speed to get great photos in the dark and in poor lighting situations. Spend $10 or so on the book, The complete guid to Sony's Cybershot RX-100 by Gary L. Friedman. I have the ebook version from Amazon. The book covers version one of the camera and is out of date regarding a lot of the setting, but it's incredibly interesting and useful. The author raves about the camera's capabilities compared with larger single lens reflex cameras he owns. He uses the camera to shoot pictures of his grandkids, etc.
I shoot mostly landscapes and nature. A few pictures of people. And I'm mostly a point and shoot photographer. But I use some of the manual settings in special situations when I'm using my RX-100.
For bird and nature photography, especially on trips to Alaska and Yellowstone, etc, you can't beat the DSC-HX300. I like it better than my older Nikon telescoping camera. Its limitation, however, is that when you telescope out into digital zooms, the pictures are not as you get with a real long range lens. So I have to keep that in mind when I use that camera.
Bottom line, if you're an Apple ecoSystem customer like me, the iPhone X is worth the money and great fun. I'm taking a lot more photos with it than I did with earlier iPhones. You can use the iPhone out of the box. I've spent a lot of hours with Friedman's very detailed RX-100 manual, and I have a lot to learn with that one.
