SunTrust is better-known for its debit cards that would earn Delta miles. I had the card for some time and was generally happy with it.
Closing my account was a nightmare, though, with several fruitless attempts.
However, some of you may already have a SunTrust checking account and the SunTrust Platinum MasterCard may be something you want to check out.
It earns 2x points on dining and travel and seems rather straightforward.
Redeeming is a straight cash deal as well, with each point worth about 0.8 cents when redeemed for gift cards. Some 'deals' give you a value of up to 1 cent like a $700 airline ticket to Europe for 75,000 points.
You are certainly better off using a Chase Sapphire card instead. You'll have a better value per point and more redemption options.
