The best Credit Card from Capital One with the best rewards is the Capital One Venture Rewards Credit Card which also has an annual fee of $95.00 but the fee is waived for the first year of use.
Other good Capital One Credit Cards with the best or good rewards are the Capital One Quicksilver Cash Rewards Credit Card, Capital One Savor Cash Rewards Credit Card, Capital One Spark Miles For Business and Capital One Spark Cash For Business.
You need to have good credit though to get the best credit cards but it's worth a try to see if you can get approved for either of those credit cards.
I have the Capital One Venture Rewards Credit Card and even though it has an annual fee it's worth it for the rewards I get from it.
