Leo says he prefers a cleaner Android experience, and as such the Nexus is pure Android with no customizations. However, while the Nexus 5 is better in almost every respect, Leo likes the Moto X because it has a few extra features that are very nice. For instance, the user can just say "Ok, Google Now" and give the phone instructions without touching it. It can do that because it has a dedicated, low power chip that does the listening. The downside to the Moto X is that the camera isn't as good. In fact, it's one of the worst out there. The Nexus 5 camera is far better. It may just come down to what carrier he has.
Robert also wants to know what Leo's favorite podcast app is on Android. Leo likes Doggcatcher, which is $2.99 in the Google Play Store.
