I had vbportal (only for a couple of days though). I removed it because I didn't like how everything was set - I wanted to be able to just put what I wanted on it, which is why I like vbhome more. Maybe if I had played with it more I could have customized it better. I think it's good if you don't want to add any content to it - if you just want it to pull things from the forums. I didn't want a page that just reiterated everything that was already on the boards.
It probably just depends on what you want it to look like, and what your personal preference is
