When I compared the two players both of them ended up having good and bad points about each other like having the choice to upgrade the Sansa and not the X-Micro F610 or having the extremely light weightiness of the F610 to the heavy Sansa, it will totally depend on the user and if I had the choice even though I think the Sansa is a brilliant device I would go for the X-Micro because of the shire lightness and the amazing audio quality which is the most important feature of a MP3 player
