How to properly benchmark and compare between 2 OS?

Hi. How do you properly benchmark and compare between the OS?
Programs such as 3dmarks and pcmarks should be used. What about Xvid Encoding and games, etc?

Which games and utilites should I use for the best and most accurate test? Thanks

You try to test some kind if generic performance of each OS? Really generic performance does not exist, best test things that are similar to your workload.
