This is my opinion before I've listened to anything on mine,
but so far I like it better than the Zip.
Bigger is better, flatter is better, too. The controls are easier to use and the screen much easier to navigate. Overall, the feel is less flimsy. My first Zip had a wonky volume rocker that was next to impossible to use to increase the volume, to the extent that I tried never to change it which was less than ideal. These controls seem more responsive. And with a longer better life, it seems a huge upgrade to me.
