Good summary. Thanks for taking the time to do the experiments and to write up your conclusions.
Shifting gears a bit, I can't speak for anyone else but I rarely take anyone's word/test results for things having to do with performance in general or any type of disk compression techniques. Perhaps I missed something somewhere but it would have been real handy to have placed a test table generator in the Resources section of an article or provide a URL to download the test data or something to make it so people can more easily repeat your tests on their own. As it is, we can't even tell what the cardinality of each column is, which could certainly have an impact on such things as compression and Columnstore.
