While there is a noticeable difference in the results of the synthetic benchmarks between the HTC One and the Nexus 4, there isn’t much on the usage front. But the difference between the Zen Ultrafone 701 and HTC One is huge. Before labeling the HTC One as the winner, we would like to point out that there is a huge difference in the overall price of all devices. While HTC One wins, it is approximately ` 30,000 expensive than the Zen Ultrafone 701. The Zen Ultrafone 701 and the Nexus 4 are still great performers.
