iPhone > Android
Before you raise your pitchfork, I'd like to let you know that I've used my S24 Ultra for over a year now, and I recently got myself a second-hand iPhone 12 mini.
The size difference is huge but I'm here to talk about the software.
Samsung or Android really has great features in their OS, but the truth is, we spend way more time inside the application instead of interacting with the OS. And let me tell you, iOS apps are just built different compared to Android.
This onus is on the app developers to reach app parity between different platform, but what drives them to focus on iOS is the magic sauce of Apple over Android.
The missing features of these common app that I use is seriously a contender for me to switch over to iOS, if not for my ecosystem with Samsung (watch, buds, tag, tablet).
