We ditched credit cards years ago. I have actually considered having one as a backup for the few days it takes to get a new card though. How would a credit card be less hassle?
Ditching credit cards is wise if it makes it difficult for you to keep track of your spending and control of impulsive buying habits. But credit cards don't create debt, people do (see what I did there). There's nothing wrong with having them and they can actually benefit you from a credit perspective. I actually don't use my debit card for anything unless I have to. Credit cards just seem to be much more secure.
