If you prioritize a top-tier camera with excellent still photo and video quality, the Apple iPhone 15 Pro stands out but comes at a premium price. For those looking for a more cost-effective option, the Asus Zenfone 9 offers a commendable camera albeit slightly less impressive, alongside solid battery life and a compact form factor with a smaller screen, all at an upper midrange price. The iPhone has iOS, while the Zenfone runs on Android, so consider which operating system you prefer. Both phones support 5G connectivity and have similar build quality, so your choice may ultimately hinge on whether you value camera capabilities and iOS enough to justify the iPhone's higher cost.

Tom's Guide
Mark Spoonauer | September 2023
"The iPhone 15 Pro is the one to get if you want a powerful flagship you can easily use it with one hand. Not only is the titanium design stronger and lighter, Apple made the design smaller with slimmer bezels. You also get very strong cameras with night mode and portrait improvements, blazing performance from the A17 Pro chip and a smart Action button."

"The Asus Zenfone 9 is a compact device that still packs more than enough power under the hood. It's compact size, Bluetooth and audio features (including a headphone jack!), and hardware gestures combine to offer a package that does enough differently to warrant your attention."

About Apple
The tech giant called Apple is synonymous with the most popular smartphone in the world: the iPhone. Known for their build quality and aesthetics, as well as for their excellent integration between hardware and software, iPhones have defined the smartphone industry ever since their conception and they continue to do so by setting new industry standards. Apple's own operating system, called iOS, is known for its simplicity and ease of use, and the company tends to complement it well by creating devices with some of the most powerful processing hardware available in the mobile world. The iPhone is also known for its robust ecosystem of accessories, as it facilitates a very seamless experience when interacting with other Apple products, more so than most of its competitors.
About ASUS
Asus is a well-known player in the mobile world, and in the past few years it has been known for covering specific niches in the smartphone market. Their Zenfone line of devices appeal to small phone enthusiasts, by providing very well-rounded and capable phones at a package that is not too large to operate with one hand – something hard to find in modern Android smartphones. Conversely, their ROG line of devices cater to mobile gamers, by providing a slew of hardware and software features, specifically tailored to enhance the mobile gaming experience. Additionally, Asus is one of the only manufacturers left that continues to include headphone jacks in their lineup of phones, a feature that has become exceedingly rare in today's market.
