NSUSerDefaults is meant to be used with strings, booleans and NSData representation of other data (serialised). I believe you serialise your class to be stored into UserDefaults which is fine.
When I started developing on the iPodTouch2G, I had issues storing and retrieving data more than a few hundred kilobytes. I took some months to understand the basics of CoreData (I never wanted to use raw SQLite, which is an option). Even today I have not mastered it because mastering core data can only happen with time and experience. I still don't like the way CoreData calls from multiple threads and the merge mechanisms but that is the way of life :)
Sooner than later your dataset will grow and you will be hard pressed for options. I suggest you start with simpler architecture (One entity with one property) and scale up the learning process.
This is a comprehensive guide to learning core data and mastering it ;) Core Data: Data Storage and Management for iOS, OS X, and iCloud (Pragmatic Programmers)! from one of the masters of core data.
Typically iOS devs at their level of polish are using core data to store information about the app entities. This is a object graph system that maps to disk, the web, a database, or really anything else.
