A solution for data pipelines but has connector limitations
We have used Kafka for seven years. IBM streams gives you many OOTB features that can boost the time-to-market, especially when it comes to reporting and monitoring for example. Confluent is recognized as one of the leaders in this space and the main reason for this is related to the complete vision of the platform also the large number of connectors. This gives the edge and competitive advatnage.

Offers a seamless way to decouple applications, providing impressive performance and flexibility
Regarding improving the PubSub+ Platform, I'm not sure about the pricing aspect, but I heard that it is quite expensive compared to Kafka. That's the only concern I can mention; otherwise, it was as impressive as Kafka, better than Kafka based on my experience working on the Solace and Kafka white paper.
