Which iPhone 5 deal is better?

A perfect condition used iPhone 5 16 GB for $460
OR
A iPhone 5 32 GB with minor damage around 3 corners and a scratch in the back (looks great when inside a case though) for $460

The second one

I would take the 32 GB.
I hate damaged phones, but that's twice the storage.

If you don't mind aesthetic go for the second one.
