With containerized flavors of these products, we are having a tough time dealing with PMRs because the versions are new to IBM.

SWIFT manager at Raiffeisen Bank Aval
Reliable payment processing is achieved with minimal disruption
Currently, we have some disadvantages; it's a bit difficult to use IBM ID to access support from the IBM site. To get nice support from IBM, we need to use IBM ID, and it's a bit complicated to integrate it with IBM support. Support can be better because sometimes we need explanations for some behaviors of the product, and it's not easy to reach the proper person in IBM support. They could add some new features into IBM MQ to make it better. A graphical user interface in addition to MQ Explorer could be useful, but we are satisfied with MQ Explorer as well.

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.
