My Choice

If I were choosing between these two phones, I would personally go with the ZTE Axon 40 Ultra. While I appreciate the compact size of the Zenfone 8, the Axon 40 Ultra's larger, brighter display, more powerful chipset, and significantly larger battery are more aligned with my priorities. I often use my phone for media consumption and gaming, and the extra battery life and more versatile camera are appealing. While the Zenfone 8's smaller size and audio quality are noteworthy, the advantages of the Axon 40 Ultra in terms of overall performance and versatility would outweigh those benefits. Moreover, the availability of 1TB storage gives me significant peace of mind that I won't have to manage storage as often as I would with a 256GB phone. While I would slightly prefer the more durable screen and extra satellite navigation, these aren't essential in my day-to-day use. The better camera versatility, specifically the telephoto and under-display camera, are more attractive to me.
