Agree to not write off the stock apps, but I personally hate Safari and the way it feels and controls. It’s genuinely harder to navigate and around webpages and it’s hard to put my finger on why. Its interface is also just super dated and not as intuitive as the other browsers. And there isn’t really any real reason to use it since every web browser on IOS is secretly Safari under the hood. It’s just the UX on top that’s different.

The Mail app has a similar issue where it’s just kinda dated and clearly hasn’t been given much love since its creation. The calendar app, Notes, weather, and others are pretty rock solid though.
