Ranked in these QuestionsQuestion Ranking
Pro Great selection of high quality and polished apps
Apps must pass tighter guidelines to make it into the app store.
Pro Consistent performance
Unlike Android, iOS is developed to be used on similiar devices and both the hardware and iOS itself are developed by Apple. This means that they are highly adapted to work with each other. Even after the hardware becomes a little outdated, the performance still remains consistent and smooth on several iOS versions.
Pro Everything works very well out of the box
It's engineered to be designed. Design means choice. A collection of best options, components and programs chosen by highly experienced curators/designers/engineers are installed by default. No need to customize. It's best by default.
Pro Easy to learn to use
The iOS user interface is known by millions. It has mostly stayed the same throughout the years.
The main view is a simple grid menu which displays all the installed applications. On the bottom there is an app tray which displays the icons for the most used apps.
The iOS user interface is especially easy for users who want an easy experience and don't want to spend time learning on how to navigate through their phones. Everything is displayed right in the main view and it's easy to find. The fact that it has not changed, at least significantly in the past years has made it possible for it's most devoted users to keep upgrading their iOS devices without having any difficulty to adapt.

Siri is an intelligent personal assistant and knowledge navigator. Siri lets you use your voice to send messages, schedule meetings, place phone calls, and more.
Available in select cars, CarPlay is built primarily around the use of Siri voice commands and prompts, providing an "eyes-free" experience where you can respond to incoming calls, dictate text messages, or access your music library from a vehicle.

Out of the box support for caldav and carddav.

Other operating systems like Android or Windows Phone (more or less), iOS isn't as customizable.
Con No file managing
Managing files and directories is not possible. Files are in fact attached to applications. It is an oversimplification that can be limiting.
Con Inconveninet price and hardware lock-in
iOS is only available on iPhone, iPad and iPod Touch, in which these device may be more expensive than the competitors.
Con Tied to Apple
No alternative software can be installed unless you keep your phone jailbroken (with the system outdated and probably with security issues).
Con Unlike Android, it is proprietary
Con Older iPhone models with poorer batteries might perform slower
iOS delibrately slows the CPU down on older iPhones with worn-out batteries so as to preserve battery life, resulting in possible slower-than-expected performance. This only applies to iPhone 6, iPhone 6S, and iPhone SE running iOS 10.2.1 and above, and iPhone 7 running iOS 11.2 and above.
Con Apple is very unfriendly regarding warrenty and repair work.
If your devices breaks, they will just tell you to buy a new one.
Con Only a few native apps, needs Android support to access many apps
Users may need to install Google Play store or other alternative android app store to access your bank's app or any highly specific app you might need.
Con Only a few available phones
There are currently only a few available phones on the market with Sailfish OS and both the Jolla and the Jolla Tablet are out of stock and unavailable.
