It features a large 6.7-inch OLED display with a 120Hz refresh rate, a powerful A15 Bionic processor, an excellent camera, and one of the best battery life of any iPhone of its generation. Its design was so successful that subsequent models retained similar features for a long time.

Another legendary device is the iPhone 6. It represented a huge leap forward with its large screen and thin design, bringing Apple record sales.

When it comes to price, features, and durability, many users still consider the iPhone 11 to be one of the most practical iPhones. It features a powerful A13 processor, a good camera, and has long been the best option for most buyers.

So there's no clear winner: the iPhone 6 is the most revolutionary, the iPhone 11 is one of the most practical, and the iPhone 13 Pro Max is one of Apple's most successful flagships.
