What message publisher should I use?

[Gigioliva]

I see that we have two ways to publish a message:

• topic.publishMessage
• v1.PublisherClient.publish

Which one should I use? and what is the difference between the two?

https://cloud.google.com/pubsub/docs/retry-requests doc uses v1.PublisherClient.publish but we can also do it with topic.publishMessage too (gaxOpts -> longrunning option).
