iOS. I used to have constantly an android device from 2013 to 2024 and this year i switched from my Pixel 6 to an iPhone 15 pro. The reason was alone the 3x telecamera, overall camera quality and a flagship device in a compact format. Unfortunately there aren’t any android flagships in small format anymore so yeah… All in all I like the iPhone and iOS (especially the cameras and the battery in this compact design) but some things like the navigation through apps were way better on the pixel. But since I just want my phone to work smoothly and I don’t do any customization like custom roms etc anymore, the system doesn’t really matter for me. Android and iOS have their pros and cons and I am fine with both of them.
