I'm not advertising for CRS here, but it is worthy to mention here that CRS has no additional cost and I believe that SG (with clustered filesystem or not) is an additional cost. I agree with your points completely as well. We should also point out that administration tools/interfaces for SG are probably less command-line-required than CRS is (currently, at least).
