Hey Dominik, com.google.api.services.pubsub comes from Google Cloud Pub/Sub API Client Library for Java, <https://developers.google.com/api-client-library/java/apis/pubsub/v1> while com.google.cloud.pubsub.PubSub comes from the Cloud Pub/Sub Client library <https://cloud.google.com/pubsub/docs/reference/libraries>. You can read about client libraries in general in the documentation <https://cloud.google.com/apis/docs/client-libraries-explained>. Basically, you can use either one when both an API client and a Cloud client library exist, but the documentation for the API client library will likely recommend using the Cloud client library, as is the case for Pub/Sub (see the first link in this reply).
I hope this is helpful in explaining, let me know if you have any other questions.
