What I would choose and why!
If I were choosing between these two phones, I would pick the Google Pixel 9. Here's why:
As an engineer, I appreciate the raw power and advanced features that the Zenfone 9 offers. However, as a tech journalist, the camera and software experience is often at the heart of what I'm trying to showcase and capture. The Pixel 9's image processing is second to none, and this is incredibly important to me. Combined with a modern OS, and a host of convenient features, the Pixel 9 makes an excellent everyday phone for me.
I value a well-rounded device that delivers consistently across various use cases, and I believe the Pixel 9 strikes the right balance between cutting edge technology, software excellence, and practical day-to-day use. While the Zenfone 9 is a very compelling device, its key selling points are not where I prioritise my needs.
The Pixel 9, to me, is more than just a phone; it's a tool that integrates into my life, not just a device that serves a singular purpose. The combination of its excellent cameras, smooth software, and long term software support, combined with convenient wireless charging, makes it my winner.
