Forefront: All-in-one or best-of-breed?

I recently talked to two Forefront customers, who had a lot of praise for Forefront’s all-in-one management console and its protection against external threats.  Any Forefront users out there? What do you think? Do you agree? What have been some of your challenges?

Also: what do you consider to be the trade-offs of going with a best-of-breed solution over an all-in-one system like Forefront?
