Why should we use Queueable apex when we can perform chaining of batches in batch apex (when we can call another batch in the finish method)
They just have different use cases.

Why should we use Queueable apex when we can perform chaining of batches in batch apex (when we can call another batch in the finish method)
Queuable Advantage:
Queueable can run parallelly and there no limit for chaining. While in a batch there is a limit of 100 batches
Queueable can be much faster than batch apex if used properly
