Good idea....
 

Let me start it out....

What is the best credit card for rewards....

Someone was going to do it!

Bankrate usually has good info. Here's the Bankrate Credit Card page. I'm pretty content with Discover -- some cash back, good service, cool card designs.

only rewards card i have is my costco american express.. it is a cashback card.. 3% for dining out, 2% for travel, 1% everything else..

I use a Discover Miles card. Its okay, but requires a lot of use to really take advantage of the benefits.

I would prefer to have cash back options instead of the simply a miles program. Perhaps one of these days I'll actually do something about it...

I use the American Express Starwood card. Points build up very fast and you can stay at any Starwood property as long as they have a room available. No black-out dates. Doesn't take many points to get a free night either.

My Phillips 66/Conoco card allows me to buy a cold drink and a snack each time I fuel my vehicle. It's like having money without actually having money. Very cool.

I like my AAdvantage MC - 1 AA ff mile for each dollar charged. We like to travel so the free airfare is nice.

Costco AMEX. Not the current one, but the old one. 2% back on Costco purchases, 1% back on everything else. Tough to beat hard cold cash.
