Well, you can't compare those two things, can you?
Bitcoin paper wallets are used to store coins safely or the case like mentioned above to give it as a gift to other people (there are various more reasons).
A Bitcoin collectible isn't really meant to serve as a wallet. 
There might be loadable coins (or similar) but you have to peel them if you send the money again and once you have peeled them, their worth is not only reduced including the amount of BTC that was stored on it but also reduced in value as a collectible. It's always sad to peel a loaded coin. 
On the contrary, paper wallets can be easily created multiple times.

So, I won't compare Bitcoin collectibles and Bitcoin paper wallets. In Germany we would say "you compare apples with pears". (not pineapples)
