Have the Moto X Play. Cost equivalent of around £250.
I'm not sure where I am missing out in comparison with the premium phones.
I also have a work supplied S6 edge, which admittedly looks and feels great, is not a "better phone" in any significant way.
Not a fan of the iPhones. The plus with the same screen size as mine, is way bigger and clumsier. And having owned an iPhone 5, I wouldn't personally want to downgrade to iOS.
I did use a Nokia 1020 for a time. Pretty nice phone, decent cam (although no where near as good as the fervent supporters would have everyone believe...and WAY too slow).
I may give Windows phone another chance next time, but for now I'm happy with a "midrange" Android.
