S600 is a new generation improvement over the S4 Pro. If it's not ahead, something is wrong.

Regarding your statement on the LCD... I can only facepalm..

Your statement of both being LCD is correct. Even my Casio watch is a LCD.

What I am correcting is the term TFT being used. Did you know that the Super LCD is still a TFT technology? It's just pretty much marketing speak, just like how Samsung calls their LED backlit LCD the LED TV... until you get people thinking that LED TV is a whole new screen technology over LCD.. =\

As for smoking the Xperia Z, yes and no. Depends on the user. For people like you who buys phones based on benchmarks and viewing the screen from the corners.. maybe. But I intend to actually use my phone, and I view my phone with it facing directly at me. And I also need big storage for all my data, removable ones. Not internal ones that are limited to MTP. So no, to me, the HTC One does not smoke the Xperia Z.
