You should get whichever suits your budget and needs best. No one can make that decision for you.
 
Well they are relatively the same price, but I do like the colour white. But my collection is almost 26GB...

do you need your whole collection? if so, then get the 64gb, because you don't really have 32gb. you have less because of the os and apps.

i make playlists and easily get by with 8gb. it's all in what you want to do, how much money you have, and memory mgmt.
