I bought that phone in 2014 with a broken screen and was intending to repair it and flip it. I ended up keeping it.
That phone was amazing. Voice commands just worked so well. When I was driving and issued a command it would know I was driving and therefore enable the speaker.
It also supported what Google now terms "trusted voice"(lets me issue command when locked and it would do it only for my voice alone), something that my Nexus 6 doesn't and for no good reason since the Snagdragon in it supports this.
Its too bad the replacement screen crapped out
