I think it depends on your reasons for delaying. If you are feeling burnt out or feeling like your lacking experience, waiting is a wise choice. That way you can buff up your experience/get some rest/work on other weak points in your application (if you have them) like gpa/earn some money to pay for it.
However, if your experience and grades are strong and you feel like you have the maturity and energy to enter a graduate program, no need to delay. It is truly a personal choice. Don't push it if you don't feel ready but don't delay it if all you need is a little more information.
