My Cricket Lumia 650 broke, and it's easier for me to buy a phone directly through them, so I went with a LG X Charge and have had it for about a week. It was a shock at first, but I absolutely love the phone now. I know, I can't believe I'm saying this. But I've turned off Google services (no gmail even, it just manages my app installs) and have everything running through MSFT. My lock screen, app launcher, email and calendar, keyboard, Cortana (full voice assistant integration), and Groove apps are all made by Microsoft and they work even better on Android.
I was really worried about switching, and the phone is very different, but it makes me excited to see just how well MSFT has adapted to the platform, and how open Google has left it. The only Google product I use (because I'm forced to) is the maps and navigation, and - I have to admit it - they complete blow Bing maps out of the water. Really, really, really good navigation features.
I can't see going back to Windows phone unless something incredible happens, but I'm still a complete MSFT fan and very happy with my MSFT Android experience. If you're forced to switch and scared, just start browsing all the MSFT apps and their reviews in the Google Play store.
