Alterna Visa Infinite Card
Some folks over at RFD seem to love this card.
2% return on spending. Not everyone is able to get 2% through their other Visa or MasterCard cards, so this reward ratio could be attractive to many.
(I myself get 2% return on the Capital One Aspire (which isn't available for new applications), and on a couple of MBNA cards (which are also grandfathered and no longer available).
If you have a lot of spend and your goal is to maximize your rewards dollars, and you only want to deal with 1 primary card, this might be a good option.
But there's a $120 annual fee.
