Can you clarify what do you mean by "rocking with OpenSolaris" ?
OpenSolaris being source code only, while SolarisExpress is a distribution based on OpenSolaris, I don't know where to cast my vote, as I use Solaris 9, Solaris 10, SolarisExpress (various builds) and occasionnaly Schillix (a 'pure' OpenSolaris distro) ...
You should probably add "both" as an answer in your poll
