Visual Build Pro vs. Team Foundation Build

[mistermoon]

Hi folks,
I just wanted to discuss with you advantages/disadvantages especially between the TFS Build and Visual Build Pro.
One big pro for the TFS-build for example is the reporting and automated email, but what if I use another repository? Then the reports won't be that detailed anymore. Why should I use one or the other?
Thank you,
MrMoon

Ps. I posted this thread at the msdn-forum (TFS Build Automation) as well.
