CMS Integration with vB... what is the best choice available?

[Pulsorock]

I've been using vB since the firsts version of 2.x, and my site with a simple CMS I created back then. At the time, there was no integration whatsoever in my site CMS and vB.

A lot has happen since then, and now I'm considering get rid of my old CMS and have a new one, with a complete website redesign, everything new.

The problem is that I have not much free time to develop a new CMS, and I was thinking to look for an out-of-the-box CMS package that offered great features and a way to integrate vB too.

I know there are several CMS and some hacks, but wanted to make sure what is the best alternative currently available for a CMS that can integrate easily with vB, and that is feature rich and easily customisable. I was thinking of Drupal, I also saw a commercial one called Vivvo. But besides these two, is there any others that integrate well with vB? Could be a commercial option or a open source one. I'm looking for the best available alternative.

Thanks!
