When using Solidworks PDM, do you still use the Property Tab Builder?

So, currently we use the property tab builder to populate our custom properties.

We are soon getting PDM and I am looking at administering it.

The question is, once PDM is running, should we use the data cards to populate the custom properties of the part/drawing/assembly?

Or still use the Property tab Builder and use that to populate the custom properties AND the data card?

Or a mixture of both?

What do you do?

Comments?
