Single rail is better and are generaly high quality unit. That said they are also more exspencive. The great majority of PSU availible have multiple current limited +12v rails. They are also cheaper and besause of that are the more widly used PSUs. Right now the top PSUs availible are single rail units from PC Power & Cooling.
