Rewards cards are hot again.

After dialing back their offerings during the credit crunch and financial crisis, credit card issuers are once again in hot pursuit of customers -- mostly low-risk applicants with high FICO scores.

If you're one of the favored, you've had some eye-popping deals from which to choose. Chase, for example, offered a limited-time incentive of 100,000 miles for those who signed up for its British Airways card. Not to be outdone, Capital One used "30 Rock" actor Alec Baldwin to promote a "Match My Miles Challenge" on its Venture Card, promising to match up to 100,000 miles that cardholders had earned with other airline credit card programs (the British Airways card was excluded, alas).

"Rewards cards have really become hot," said Bill Hardekopf of LowCards.com, a credit card comparison site. "The major issuers are becoming more aggressive in securing new credit card customers, especially those with good to excellent credit scores."

The offers also have improved for those with less-than-sterling credit scores, which these days can be anything less than a 740 FICO. But don't expect to be dazzled, credit card experts warn.

"There are still plenty of offers out there with average or even sub-average credit scores," said Tim Chen of NerdWallet, "but we don't see these issuers pushing rewards and signing bonuses."

Keeping up with these ever-changing deals isn't easy, so I asked four industry experts -- Hardekopf, Chen, Curtis Arnold of CardRatings.com and Ben Woolsey of CreditCards.com -- to nominate their favorite plastic in three rewards categories:

  • Travel. These cards generally offer the richest returns but only if you get the right card and know how to use it. If you're an infrequent traveler or not looking for upgrades, a different card might be a better fit.
  • Savings. This category encompasses a variety of cards that help you put aside money in an investment plan, pay down your mortgage or get discounts on major purchases such as cars.
  • Cash back. These cards are a good, simple choice for many, kicking back up to 5% of certain purchases.

The cards noted below as winners were nominated by at least two of the four experts, although a couple of cards won unanimous praise. Honorable mention cards were singled out by one of the experts as worthy of consideration.

Before we proceed further, understand that rewards cards are best used by people who don't carry credit card balances, because these cards typically come with high interest rates. If you're not able to pay your balance in full every month, check the sites above for a low-interest rate card instead.

Now, on to the results:

Travel

A clear winner emerged this year: Capital One's Venture Rewards, nominated by all four experts. Three of the experts liked the Citi Hilton HHonors Visa Signature card, and two of our experts cited the Citi Gold/AAdvantage World MasterCard. Last year's winner, the Starwood Preferred Guest Card from American Express, wasn't nominated this year.

"While the Starwood AmEx gets the most press for being the favorite in this category, I would rather have the Capital One Venture Rewards card," said NerdWallet's Chen. "The Starwood card does have one of the highest rewards payouts of any card we track -- around 2.3%, by our estimates -- but these points are primarily useful for 'travel hackers' and people who stay in luxury hotels."

The experts praised the Venture Rewards card for its simple, flexible structure. Every purchase earns a 2% reward, which can be redeemed for travel expenses on any airline, hotel or rental car, with no blackout dates and no exceptions. The card also charges no foreign transaction fees; most cards tack on a 2% to 3% charge for these, so international travelers can really save. The $59 annual fee is waived for the first year.

"There are no caps on points or spending thresholds, you can redeem for any travel expense and you earn double points on all purchases," CardRatings' Arnold said. "Those features make this a good card for a much broader group of consumers than most travel cards. You don't necessarily have to be a big spender or travel often to get your money's worth out of this card."

Plus, "it's a Visa, and will be more widely accepted around the world than an AmEx card," Chen noted.

The Citi Hilton HHonors Visa Signature Card has a good sign-up bonus, the experts noted. Users can earn 40,000 Hilton HHonors bonus points after spending $1,000 within four months of the account's opening. Plus, they earn:

  • Six bonus points for each $1 spent at a participating hotel within the Hilton Worldwide portfolio.
  • Three bonus points for each $1 spent on purchases at supermarkets, drugstores and gas stations.
  • Two bonus points for each $1 spent on all other purchases.

And there's no annual fee.

"I like this card because of the great sign-up bonus offer and the ability to rack up points fast," Arnold said. "It's nice that the card allows you to earn bonus points in non-travel categories as well as double points on all purchases. Not having an annual fee also sets this card apart, since most travel cards with a robust rewards program currently have an annual fee."

The Citi Gold/AAdvantage World MasterCard is another card with a better-than-average sign-up bonus: 30,000 American Airlines AAdvantage bonus miles after $750 in purchases within the first four months. Users earn one AAdvantage mile for every $1 spent, and the $50 annual fee is waived for the first 12 months.
