The fact that it’s also priced more affordably makes it an even more attractive option. The trade-off is the larger screen and overall better brightness of the Flip 5 but that is a trade-off I would be comfortable making.

Ultimately, both are excellent phones, but the Zenfone 9 fits my specific needs and use cases more seamlessly.
