Bitcoin's offering financial transactions with very low fees compared with banking services and using fiat or other currencies, and that's powerful feature of Bitcoin
That's true we can send money across the world with least fees and that is the best feature of bitcoin, as banks charges are too heavy and transaction also takes time.
I think for transaction banks are very fast compared bitcoin, which may make long is a process that must be in line. But it is true we can buy what we want without swapping with first dollar and the price is not too expensive. That's what I really like.
