Android phones, apps and tablets

Google and android are starting to piss a bit on my chips. Still prefer it over the iPhone 5s I think. What's the best android phone out there right now. Need to choose a new work phone and dunno to get a N5, HTC One or a S4.

I think the S3 is still a great phone and cheap nowadays. However if work are paying for it go and splurge the dosh.
