The Nexus 5 is Google's current Nexus smartphone. For those that are unfamiliar with the term, Google's Nexus branding means that the device runs stock Android software without the crazy manufacturer user interface. HTC's One M8 utilizes the company's Sense 6 skin, for better or worse.
The Nexus 5 also receives updates straight from Google, and comes with an unlocked bootloader which allows for intense customization. HTC's device is dependent on carriers in the United States.
Best of all, the Nexus name stands for affordability. Google's Nexus 5 starts at $399 unlocked. By comparison, the HTC One M8 starts at $700 unlocked. This $300 price difference is notable because the Nexus 5's hardware is extremely powerful, just like the HTC One M8's.
We consider the Nexus 5 one of the premier Android devices on the planet and it's a device that we think you should check out before going with HTC's flagship. There is a lot to like about it especially the vanilla software. Those that need more information would be wise to check out our Nexus 5 review.
