The most popular among these tools are Orange, Knime, RapidMiner and Weka.
I have previously checked out Knime in 2015 but didn't attempt much with it. This time I will use them all on some live jobs I have got. I will be testing them intensely and going through their strengths and weaknesses.
I will also be sharing my findings with you all. If you want to follow along you can install them too or just wait for my posts to determine which would suite you best.
