If you use your smartphone to mostly browse the web, use google apps (gmail, hangouts, gmaps, youtube), and don't mind waiting 6-12 months for the hot new app to come to Android, the MotoG is a fantastic device. The LTE version is just $220, and I don't really see the point of paying 3x the price ($650) for an iPhone.

Also, Firefox is the only mobile browser that allows extensions and it's only supported on Android, so you can install Adblock Edge and browse the mobile web free from any ads!!
