They just have different use cases.

  • Most crucially, you can have only 100 batch jobs pending at any given time. I do not believe any such limit exists for Queueable jobs.
  • Queueable jobs will also tend to execute faster as they have less overhead to deal with (no start/finish).
    • Generally, batches should be used to act over moderate to large database queries, whereas Queueables should be used to execute smaller increments of work more quickly.
