We know you aren't here expecting a comparison of both the devices, but still in a nut shell, if you want performance over looks, Galaxy S4 is the phone to opt for. Instead, if you want a phone with awe-inspiring looks and with a great (but still less than S4's) performance, you better get yourself a HTC One. Another deciding factor here can be your specific taste for Touchwiz or Sense, the User Interface featured by Galaxy S4 and HTC One respectively (My vote goes out to Sense).
