it's not really all about hardware I have to say. The DUOS hardware is not screaming but its not bad. The software has been very well optimised for it, and the overall experience is very good.
One of the problems with Android Dual Sim phones in general is that unless the user has good knowledge of Androids (rooting, customization etc), its very difficult to get the best out of any device. Not to mention most of the good ones are targeted for Chinese release, which makes then hard to use unless installed with customised ROM. and the Galaxy S DUOS (and international version of Desire V) has taken that hassle away from users.
Also worth mentioning that Galaxy S DUOS is made for European market.
U960 is a great dual sim phone but it's just a bit too dated, and lack of manufacturers support. In contrast, Galaxy S DUOS is considered latest line of device from samsung and is scheduled to be upgrade to Jelly Bean OTA soon.
