You can generally use a credit card anywhere in the world. If you pay in bitcoin then you will need to trust the merchant you are buying from as you cannot reverse the transaction.
The main selling point that bitcoin has above credit cards is the cost of accepting/processing credit cards. Since the cost is lower when paying in bitcoin, merchants are likely to pass along these savings to the consumer.
