My preference is deep links to internal content hub pages. 1) Gives me an alternative location other than the home page to promote site content, and I can theme the internal hubs to the specific widget. 2) Makes it a little harder for competitors to see all the links that help me.
I have been thinking my preference is a bit old school and it does not match Bing's SEO recommendations of three links deep from home page (if they only consider one page as a site "home" page). But Bing is not Google and I deal with Bing separately.
