KNIME vs SAS and Alteryx

Dear users,

My company is now in a tool research project analyzing the features of KNIME/SAS/Alteryx for Marketing purposes. 

We are now using SPSS Statistics but want to move to a more robust and user friendly tool which makes portability of projects to other employees easier, requires less manual coding and easier to work with. 

From the tools we have seen KNIME seems the best fit but because it is open source the IT staff is a bit reluctant to implement as the support might be less than they are used to. 

What are your experiences with KNIME

  1. in terms of features in comparison with other tools e.g. SAS/SPSS/Rapidminer?;

  2. in terms of support;

  3. in terms of features, is it easy to get used to for example;

  4. what are your biggest pros with KNIME?;

  5. what are really turnoffs with KNIME?

Hope you can help me out with this as we are 'lost'.

Regards,

Rishi
