AWS Managed Apache airflow (MWAA) or AWS Batch for simple batch job flow

Question

I have simple workflow to design where there will be 4 batch job running one after another sequentially and each jobs is running in multi node master/slave architecture.

My question is AWS Batch can manage simple workflow using job queue and can manage multi-node parallel job as well. Now, should I use AWS Batch or Airflow ?

With Airflow , I can use KubernetesPodOperator and job will run in Kubernetes cluster. But Airflow does not inherently support multi node parallel jobs.

Note: The batch job is written in java using Spring batch remote partitioning framework that support master/slave architecture.
