The solution works better than MuleSoft, Dell, WSO2, etc. Also, it is highly effective when integrated with an old legacy system in the EDI format using WTX, a mapping tool, compared to other solutions.

We looked at another solution called WSO2. It is a lot easier to set up. It's easier to use, and it's less expensive. However, the challenge we have with that, is that the support is lacking as it is an open-source application. The support is not so strong. That's the only reservation we had for that. Outside that, we are also using it for some other applications as well.

The prominent other contenders were WebLogic from Oracle, and whatever was provided by Microsoft. Among the three then, IBM came out on top in our assessment and rating. However, with the benefit of the insights we now have, if we were to do the same process again, over five years, WSO2 has done so well, and some other middleware is also doing well. Likely we would not choose IBM if we had to choose again.

We evaluated other solutions.

We also work with TIBCO and Oracle ESB solutions. We find that our customers have had a good experience with them and there is always a lot of interest in these two products.

Most of our products are IBM, which makes it easy to integrate them.

We evaluated Mule ESB. We didn't consider because:

1. Mulesoft was relatively new. Hence, it lacked skilled resources.
2. The cost was high compared to IIB.
3. The client had a good relationship with IBM. 

We evaluated several similar products including solutions from Oracle and Software AG, and we chose this solution not only because of its technical features but also because of the on-site support that IBM gave us.

We have gone through different comparative solutions and other integrated systems, and IBM Integration Bus is better for enterprise.

We did evaluate other products before going with IBM Integration Bus. 

I like to view comparisons to see what people have to say about similar products because I have just recently changed jobs and my new company is trying to purchase an ESB. Although I fully recommend IBM Integration Bus, I think it is important to look and see if other solutions may be better.

We have evaluated other solutions and we have found that IBM solutions to be highly stable and scalable.

We also evaluated Oracle.

I have evaluated MuleSoft.

While evaluating IIB, we also evaluated Oracle Service Bus (OSB) and the latest version of Microsoft Biztalk Server.

I have heard of MuleSoft, a platform that provides a solution for API management, ESB, everything. When it comes to ESB, they have a package or facility feature for unit testing as well, called MUnit or something. From an ESB development point of view, this is the complete package. I was lacking these features in App Connect, but I heard that the latest version includes things like unit testing, automation features, all those things. I also heard that they added AI—I'm not sure where, but IBM is pretty big on that, as well as on adding more and more features in that area.
