Just the Maxx? Not Maxx HD or Razr Maxx?
Go with the LG G2. Better screen, better CPU, GPU. Better camera. Dolby sound. Higher version for stock ROM. USB on the go. FM radio. You give up splash resistance, barometer sensor and removable battery if you don't get the Maxx. None of those would be deal breakers for me.

Removable battery?
