I don't think that Christopher Moltisanti would be a suitable Boss for the DiMeo Family; he's simply not intelligent enough to be it. I think, however, that Silvio Dante would be a much more suitable Boss for the Family, although, he is not the most intelligent member of the DiMeo Family either. I think that Jackie Aprile was probably the most suitable Boss for the Family throughout the entire six seasons of The Sopranos.
