IBM Cloud MQ Point-to-point or Pub/sub?

Question

I'm writing an application that will trigger a task after getting a message from a queue on IBM Cloud MQ. There will be only one producer, and only one consumer (the app i'm writing. Because of this, I thought it was better to use a point-to-point strategy instead of pub/sub. However, while I can use an HTTP REST Get action to get messages from the IBM MQ queue, I would also need to periodically execute a GET to "monitor" the queue.

Wouldn't be better to simply use a pub/sub strategy if that's the case? I don't see the advantage of using point-to-point, although the documentation advices it for my use case.
