We work as developers and create interfaces. We're doing both interactive interfacing with other applications and enterprise applications. We also do some of the middleware.
Both WebLogic and WebSphere are only as good as the people making the general design work and the programmers doing the code and the job needed. WebLogic is a good framework to work on. I've been in computers for over thirty years, so compared to what we were doing back in the day, it has an ease of use that we never dreamed about years ago.
As far as being able to go from business logical processes, user stories, or requirements, into actual working code that connects the different data streams, databases, and data lakes, it works well. We can connect our data logically into a working application solving problems much more easily.
WebLogic's and WebSphere's functionality depends on what you use them for. If you come out of an Oracle house, you like WebLogic, and you will like Web Sphere if you come out of an IBM house. There are significant differences except for some of the commonalities of code you would be pulling from based on legacy-type things.
