Most powerful chip is hard to come by in small Android phones and often not really needed/warranted. I think you'll get poorer performance a couple years down the line (which is, I expect, the reason you're wanting the best chip) if you have to deal with Samsung touchwiz and bloatware vs. bare, unlocked Android. The Motorola One lineup checks all my boxes right now: Stock Android with unlocked bootloader, uSD card, good displays, good battery, headphone jack, stays updated, and under $400. I'm mourning the loss of swappable batteries and small displays in the market, but it's the best option I've found.
