I too had a Nexus 4, as well as a Galaxy Active and iPhone 5. I am really enjoying the Moto X in contrast to those phones. The Nexus didn't have LTE, so that was a given upgrade, the Active was big clunky and has too many extras which cant be deleted and rarely used, and the iPhone 5, well I have all things apple, and decided I wanted a different experience from a phone, hence my move to Android. Moto X is a stock android phone, I dont care what anyone says...it is not filled with all kinds of fluff, and the things it does have arent even enabled until you agree to do so...upon boot up of the moto x for the first time, its as plain as plain gets. If I was never given a spec sheet, I would think this phone performs as well if not better than the leading competition. Benchmarks etc. on a phone are a little ridiculous, who cares what scores it gets, I just care whether or not there is lag, what apps are available to make my day to day life productive and do it well. Moto X accomplishes that, and its why I moved to it. As I get to know the Moto more, I am sure I will like it better and better....
