If having a top-tier camera is important for you, the Asus Zenfone 9 provides better overall photo and video quality, including features like RAW output and HDR video, which are absent on the Motorola Edge (2021). However, the Motorola Edge (2021) offers a slightly longer battery life and a larger screen than the Zenfone 9, which may be preferable if you consume a lot of media or play games. Both devices have similar storage capacity and the same operating system, but the Edge (2021) generally costs less. Therefore, if budget is a concern and you can compromise on camera capabilities, Motorola Edge (2021) might be a more suitable choice. Give Feedback

"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."

Philip Michaels | October 2021
"If you've overlooked Motorola's higher-end phones in the past, the Motorola Edge 5G UW does a very good job at trying to regain your attention. Improvements to the main camera impress. I'm also impressed by how quickly the phone recharges. It's the affordability that ultimately wins the day for the Motorola Edge. this phone offers enough premium features to put it at the forefront of midrange options."

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.

About Motorola

Motorola, a well-known name in the smartphone world, has a long-standing legacy in the industry, with a history dating back to the early days of mobile phones. The brand is mostly known for striking a balance between affordability and functionality, as well as providing a clean and straightforward interface with their software skin on top of Android. While they have traditionally been prominent in the budget and midrange categories, Motorola has also occasionally ventured into the high-end category for smartphones.
