Room For Improvement

Users seek improved Python integration, scalability, documentation, and deep learning capabilities in Weka to enhance usability and performance.
I believe that the owners of IBM SPSS Statistics should think about improving the package itself to be able to treat unstructured data.

I'm unsure if SPSS has a commercial offering for big servers, unlike KNIME, which does.

I think Weka needs to improve in integrating Python into Weka, which would help users much more.

Setup Cost

IBM SPSS Statistics is costly but justified by comprehensive features, with pricing concerns and special deals for universities noted.
Weka is popular for its free open-source availability, adaptable for academic use, with a paid version for enterprise features.
My experience with pricing, setup cost, and licensing for Weka is that I think it's a fair price since we are using it academically, so it is completely free to download and use.

Advanced predictive analytics have supported my research and student projects across many methods
The only function I may need to be added or hope to be added to IBM SPSS Statistics is how to treat unstructured data. This mainly exists with IBM SPSS Modeler, but I do not think it is able to treat something like videos and similar content unless you are using languages like Python inside IBM SPSS Modeler or inside IBM SPSS Statistics. For the menu itself, for the selection, it does not exist. Thinking of the future, I believe that the owners of IBM SPSS Statistics should think about improving the package itself to be able to treat unstructured data.

Data mining projects have become faster and visualization now guides our pattern discovery
Weka can be improved in some areas. As a one-year user, I can share my experiences. I have tried installing other packages into Weka using the inbuilt package manager or adding modern algorithms that I wish to apply to my data sets or data processing. I think Weka needs to improve in that and also in integrating Python into Weka, which would help users much more. I chose eight out of ten because we need improvements in Weka, such as installing inbuilt packages. Weka uses skips such as N+2 or N+4 and eight-node, which makes sense basically, but I think it should improve in the package attribute, such as configuring Python easily and adding modern algorithms into Weka more easily.
