Let's check what one can term as a good credit card deal. A credit card deal is good if it works for you. So, if the credit card fits into your lifestyle in a way that rakes in maximum benefits for you, that is a good credit card deal. The most important thing to realize here is the word 'your' as in 'your lifestyle'. So logically speaking there is nothing like a good credit card deal. What it is - is good credit card deal for 'you' i.e. the individual who is going to use that credit card. This is because the lifestyle and the needs differ from person to person (and that is precisely the reason why every credit card supplier offers so many different kinds of credit cards). It might be true in some cases (where the lifestyle of two individuals/friends is similar) that the credit card deal which is good for one be good for the other too, however, this is just in a few cases.

You can always check with your friend who has recently got a credit card deal, since that might cut down the time needed for researching/hunting-for a good credit card deal. However, it's really a matter of evaluating your own needs. If you travel a lot and to far off places by air, a card that offers you good rewards/rebates/benefits on travel would comprise a good credit card deal. Sometimes the airlines themselves have their own credit card issuing/supplying company from where you can get a good credit card deal. For people shopping at a particular retail store or a shop, a good credit card deal would be a card that offers discounts, rebates and rewards on shopping. Again, the retail stores themselves might have credit cards on offer that could be beneficial to you. Then there are credit card deals that are linked to gasoline stores or big grocery chains. If you don't have any specific needs, you might use a general purpose credit card that gives reward points on every purchase you make on your credit card. These points can then be redeemed for cash/rewards. Hence, this card could become a good credit card deal for you.

Good, for credit card deals, is really a relative term and there is no credit card deal which is equally good for all.
