I'm a HTC fanboy arguably, however I disagree and agree with you. Here's my thoughts on the GSIII versus HOX:
Software: Sense 4.0 is certainly better than TouchWiz and there really is no arguing about it. It's things like the ability to set Scene's and Theme's and get a real personalization of your phone. On the other hand TouchWiz feels snappier, but it's starting to feel dates. It's extremely lightweight and barebones and the killer for me is that it doesn't offer much more functionality than Vanilla ICS, therefore why bother. The Keyboard and Messaging application on the One X is much more useable and better looking than the GSIII and the Mail application is bliss compares to the GSIII too.
Design: The GSIII design is really dates in the respect that you could erase all branding of 'Samsung' from the GSI AND GSIII, but if you put then alongside you would still be able to guess one was the others successor. With the One X and Sensation, there's not much that looks the same. The buttons have changed, the Camera location etc, which brings me to a flaming. Who the hell at HTC was allowed go design a raised camera lens? Put the thing down on a table and it scratches SO easy!
Camera: I don't think there's much in here for either of them, both phones use 8 MP sensors and I must say myself, I'm not really into camera's. If anything I'm slightly disappointed that both companies failed to improve either camera. The One X uses an 8 MP like the Sensation (despite being a different camera) and the GSIII uses the exact same Camera as the GSII, which in my experience wasn't actually that good. When it comes to the camera at least HTC have made a slight improvement by bumping the camera to 1.3 MP, however for some reason Samsung downgraded theirs, the GSII used a 2.0 MP sensor where as the GSIII uses a 1.x MP sensor.
The whole 'designed by nature' thing just goes right over me. I'm sorry but it looks like a bus run over a clay mould of a GSII and the GSIII is the stretched & curved result. The hardware buttons (as in the Menu button specifically and Hone) are well out of date in the respect that the One X no longer uses a Menu button, however the GSIII has that physical Hone button and the Menu button, basically a 2011 phone design.
Overall I think the Samsung GSIII is an extremely over hyped phone. It is ugly, but then it's old looks. I think the only thing to shout about is the processor, which is arguable better than the HOX's, however where are you really going ti ever see that improved speed? This may seem biased, but it's just my personal opinion.
