My Choice
I would choose the ZTE Axon 40 Ultra. While the vivo V21 5G has a more comfortable form factor and a high-resolution selfie camera, the performance difference is just too significant to ignore. The ZTE Axon 40 Ultra is a far better phone for demanding tasks such as gaming, media consumption, video recording, and multitasking, which are my main focus.
The larger, brighter, and higher refresh rate screen also is a plus, especially in bright sunlight. The significantly faster charging would also mean less time waiting for the phone to power up. The camera system on the Axon 40 Ultra, while not having dedicated macro and ultrawide lenses, is significantly better with the telephoto lens, better main camera sensor, and much better video.
While the Axon 40 Ultra is heavier, I would prefer the better performance it offers. Additionally, having more storage and RAM is always welcome, making it a future-proof device. Overall, the ZTE Axon 40 Ultra offers a better experience in my eyes.
