Welcome. Your are an old and new member all at once. The answer really depends on your usage. Yes you have the 300 credit, so figure if the other services are worth 150 to you. As you will be using and paying for it.
As you will learn, the credit card discussion board, in an existing discussion is were your question should go so other ppl can find it in the future and make use of the response.
Have a great day.
