I currently have 3 cards, which all get heavy use. Amex membership rewards, SW Rapid Rewards Visa and US Bank Travel Perks.

SW Rapid rewards is key for me due to regular travel to Denver from Fort Lauderdale.

I have considered the Capital One Rewards card. Other than the funny ads, I had ignored double miles, no black outs, etc. I like US Bank card I have, but it is hard to imagine the Capital One card is not a ton better. Also, I was looking at the Starwood Preferred Guest Amex, but I do not see the upgrade ver the current membership rewards account, which allows me to move miles to Starwood (although perhaps that does not have the same perks as the APG Amex, like flights besides hotels only).

Does anyone have some decent advice on these other cards?
