Teamsite 6 - worth it ?

System

Hi
we have been having ongoing problems with Teamsite V5. interface is bad, open deploy has problems, users find it confusing etc etc

We are now at a point of having to upgrade - but as a Developer and manager of a team that deals with angry Teamsite users every day I wonder if moving to V6 will be any better.

Has anybody converted to V6 ? Is it worth the move ?
Your thoughts please

thanks
regards
