 The latter looks good! The balance went from 1,000,000 to 1,000,003 ether. But what happened to the first account? It appears to have lost slightly more than three ether. Alas, nothing in life is free, and using the Ethereum public network requires that you compensate your peers for their supporting role. A small transaction fee was deducted from the account making the transaction to the tune of 21000 wei.
