Answer 5

If it is commercial software the following two are awesome

1. SAS
2. SPSS

Answer 6

Another very powerful opensource tool is Knime. In some respects it is better than RapidMiner. As for commercial here's what I've tried:

1.Polyanalyst
2.SPSS Clementine
3.Kxen
4.Statistica Data Miner
5.MATLAB

I like Polyanalyst the best. But it's just my opinion.
