call the MSTR and the BO AE, I'm sure they have lots of verbal and written comparisons.
But my suggestion to you is to do some hands on testing. MSTR has a free eval you can download to try out, force BO to do the same. The only way you will find out the truth is to do it yourself. Everyone is too busy SELLING to you.
In your test, make sure to simulate a real life environment. It makes no sense to do hands-on if the testing is not realistic. Eg, what works with 20MB of data, may not work with 20GB or 200GB of data.
- usability
- scalability with a stress test
- maintenance
- administration
