Which credit card? Well, you can spend hours searching and weighing various options. You can chase down 0% financing and then transfer your money when the rate goes up. You will drive yourself crazy and may mess up.
OR you can follow my advice. If you are SURE you can pay off each month, you should get a free card with a rebate.
If you might EVER be late in payment or carry a balance, then you should get a card from your credit union. They offer consistently lower rates and are more apt to negotiate with a cardholder than the big scary companies with the arcane rules.
Not eligible for a credit union? Guess again. I became a member of the Postal Employees Credit Union by asking if non-workers could join.
Now you can spend your time appreciating the universe.
