What type of person should consider a credit card with rotating quarterly categories?
Someone who has the time to look at the rotating categories and put the effort into the best cashback would be the best candidate. Most people, however, do not take the time to optimize the categories and therefore, are better off with a flat cashback percent.
Is it generally better to have one credit card with rewards and 0% introductory APRs, or a rewards card and a 0% card?
I like to separate the rewards and the 0% APR. The best use of the 0% APR is a long term financing of something expensive (for example, new kitchen cabinets) that can be budgeted and paid off over 6-18 months. The best use of the rewards card is cashback. If someone has the cash then they should pay for the item and get the rewards. If they do not, then a 0% APR is the way to go.
