I really like the HTC One. I also really like the Galaxy S4. And the Optimus G Pro. And that's because there are a lot of great Android smartphones out there right now, and really, none of the very best ones are actually bad (nor are any of them perfect). And if I were to ask you, our readers, what would be the first thing you could change about any of them - if it could be just one thing - a few months ago the consensus likely would have emerged as "give them stock Android."
Well, we're two out of three - the HTC One and Galaxy S4 are both available in stock Android iterations, aka Google Play Editions, and are yours for the buying (if you're in the United States - admittedly a major caveat).
