I've tried Watson; I didn't find it particularly useful, but I did think that the visualisation and interface was superb. Most of my playing with it was focussed on the 'Explore' parts, not the 'Predict'/'Assemble'/'Social Media' functions. I was disappointed in the level of documentation for some stuff (you have to look quite hard to find a definition of 'summary' - on my data, it just sums the column, for example). I was also disappointed that you can't fit distributions or access the distributions that Watson fits, and at the lack of statistics (you can't get at skewness, kurtosis and so on).
