That is a very open ended question, which depends on your engineering dept. structure, how your design/engineering process works.
We use the basic one that comes with the software. I cannot express to you how it has improved our design process.
We have a small company with 8 engineers sitting right in one area. So we are able to work pretty smoothly since we can turn around and coordinate work.
The checker engineer is in another office, and he will tend to screw things up with vault (long story short) A) does not use the program correctly B) doesn't communicate when he is checking out parts of a project that someone else may be working on at the same time, without updating from vault . Then over writing someone elses work.
If you copy designs frequently or rename parts frequently, Switch to vault as soon as possible. It has dropped days out of our design process.
Cheers
