I just started to look into datafeeds and just own one datafeed site so my opinion here is more or less theoretically
the problem with using datafeeds is: everybody is using the same feeds (like you and me!) While most tools dont allow to mix different resources this tool does
but then you could use Kurt tools like fatbomb + blogbomb (e.g convert the datafeed into rss and use it with blogbomb)

Since you have lots of content variety/mix here it could mean an advantage over people just using datafeeds and you could also SEO each and every page which is a mess with WP!

On the other hand WP blogs are getting indexed more easily....

soŽ... the best approach could be in doing both:
try using wp and this or other plugins and try kurt ideas (I still have to wrap my head around most of them) and see what works best for you
and most importantly SHARE your experience with this with me and others this way we all could save some time along the road to success..
