Difference between lightning events and aura:method

Please advise me which one solution is better for communicating across components. Because for me they are similar to each other.

Hi Artur,
  • Application events are really expensive.As a best practice, it's recommended to avoid them unless you need them badly. It's reserved for something that's needed across the application.
  • aura: method is a great alternative.It keeps code readable and maintainable and there is less code needed.
please refer the below link for reference. hope it helps.

Please mark it as best answer if the information is informative.so that question is removed from an unanswered question and appear as a proper solution.

Thanks
Rahul Kumar
