Discover has better "rewards"?

If you're familiar with Dave Ramsey, you always hear him talk about cutting up the credit cards, a plastectomy as he calls it. Well Discover got the bright idea of doing the same thing, only doing that to all of your other credit cards because their's is the only one you need since they have better "rewards". I used to have a Discover card as well as a Capital One and Bank of America card. I had my plastectomy a couple years ago. Now there is far less temptation to spend money I don't have. The only open account I have with a Visa logo on it is my debit card from my bank.
