I'm ready to take the plunge with first smartphone within one week! My partner got an S3 several months ago and I have (thanks to her) used and tested it extensively. Initially I was thinking S4 which is available here tomorrow, but after talking to some folks and seeing one and previewing some specs (with audio quality a big factor) the HTC One looks very good and competitive. So apart from the glossy info, what factors should I consider? (1) must have all the great DLNA capability that the S3 has and must interoperate with S3 easily (NFC, S-beam or equivalent) (2) great headphone audio and ability to stream from/to network shares (like the S3 can).
This is an intense topic with no right answer no matter what you read or who says what. They are both excellent phones and neither is a mistake.
I have an S3 and it has been the best phone I've ever used, so I am naturally inclined to want the S4.
I am currently using the One during my remorse period with AT&T so I am quite familiar with it.
Making a choice really depends on how and what you use your phone for.
If you value looks and feel, the One is clearly better. It is extremely solid and nice to hold and feel. If you will listen to games/music thru the speakers, the One is the best ever. If you take mostly indoor, dim lit pics, the One is better.
For me, I don't use my phone as a fashion accessory so aluminum versus plastic isnt that important to me and my phone is always on vibrate and I listen to music thru headphones so the main strengths of the One dont suit my usage.
The S4 takes superior pics outdoors, has a larger, equally vibrant display, more bells and whistles(if that's your thing) and will likely have a wider array of cases and accessories available for it. Also, the S4 allows for many more customizations(if that's your thing) whereas the One is very stripped down and bare bones. Again, personal choice.
If you liked the S3, the S4 improves upon it in virtually every area.
