LWC - pubsub or custom event
LWC - type of communication we should use
Scenario - we have two child components (siblings) inside a container/parent component. Now if the two siblings want to communicate between each other, what's the best possible way -
1. Pubsub
or
2. Child 1 fires a custom event and the parent again passes the required data to child 2 ? If possible , is this a good practice?
Please let me know the best practices here. Thanks in advance.

You can use the PubSub insted of your second approch.
But also pubsub is old way. You should go with the Lightning Message Service.
