I would say for ease of use the nano would be your best shot, like everybody said, they are #1 for a reason. But I do love my zen v plus, its not as easy to work with as my 40g ipod but its super light and easy to throw in an armband and run with. So if your at all active maybe the zenv would be good, but if you have the bucks, the nano is easier to work with and almost just as small.
