My Choice: Vivo X100
While lacking video recording specs for the Vivo X100 makes a fully informed decision impossible, based on the available information, I would choose the Vivo X100. The significant performance difference, superior display quality, and future-proof hardware are compelling. I prioritize a smooth and responsive user experience, and the X100 clearly delivers in that regard. While longer software support is valuable, the performance gap is substantial enough to justify choosing the X100, assuming the price difference isn't exorbitant. I am willing to accept potentially shorter software support for a significantly better day-to-day user experience. The vastly superior screen also greatly enhances media consumption and overall enjoyment of the device.
