vBIndex or vBAdvanced?

[Brew]

I'm about to switch our site to a portal system with vBulletin and I've come across vBIndex and vBAdvenced.

I'm at a loss as to which one is better.

I rather like the ability of vBAdvaced to use modules but how many people are creating modules for it?

Which one has easier to use admin options of block placement?

Do they have the ability to run php inside blocks?

Which is the better mouse trap?

Thanks!
