"best" in this context is obviously hugely subjective, but I'm disappointed that it's just a list of flagship offerings from the biggest manufacturers. No apparent consideration for more esoteric and interesting definitions of "best" that could include handsets such as the Photon Q (has a slideout hardware keyboard), Yotaphone (has a second e-ink display for ebook style 'always on' things), or Moto G (insanely cheap for a smartphone).
The Android ecosystem is so much bigger than the marketing budgets of Samsung and Sony might like to imply.
