In general, the fastest transfers should be obtainable by those coins with the fastest average block confirmation times.  That being said, block confirmations are probabilistic and the more established chains also tend to have higher difficulties and less fluctuation.   The other thing is, you are never actually transferring wallet A to wallet B but from address X₁ to address X₂.

 Ethereum and its various spawn have a 15 second block time; probably the fastest - you can start your own list with that and educate us all when your done.  Homework assignment!

edit.  I already messed up!  Fastcoin is the fastest with an average block confirmation time of 12 seconds.  Okay so you have the first two for your list (plus all the variations of Ethereum... so your almost done)
