I have owned two devices. They are HTC One X and Galaxy S III. Two of the devices are great but I finally choose One X be my only phone. I am not a application designer, so I need a phone that for personal use. I think HTC Sense is the most suitable UI for me to use. I also recommend bussinessman to use. The design of GS III is really really ugly but the performance of GS III is really really fast! The way I choose is the design of the phone more than the performance of the phone. One X's performance is quiet similar to GS III. I finally give up the GS III.
