In my opinion the GS4 is the best to date. I spent days reviewing forums, videos, and checking them out in store and S4 was my choice for a few reasons. It's got the fastest processor, best camera, great battery life with removable battery and SD card, and more bells and whistles than anything else out there. The majority of people put a case on their phone so the plastic on it compared to aluminum on HTC One isn't a big deal to me. I think the HTC One is getting better reviews because everyone is falling for it for it's style, speakers, the aluminum body which feels a little more sturdy if you're not using a case, and out of the box the HTC One's UI might be a touch more responsive because it's more simple. I actually use quite a few of the features on the S4 like the motions, air gestures, the build in pedometer w/ S Health app, multi window mode so i can browse the web while watching a Youtube video at the same time, and the IR blaster remote control is sweet, although i know HTC One also has the IR blaster. If the Galaxy S4 had 2 front speakers and a little more sturdy construction I don't think it would be a contest!
