I think Google provide more preference other independent hosted sites than blogger blogs to place in first page? Is it right?
blogger blogs often do not rank well, especially for mid-high competing keywords. If you have to use free methods go with squidoo or hubpages because they rank a lot better.
I've seen blogger blogs rank extremely high because of their value. "Type" has nothing to do with it. Value and traffic has everything to do with it.
I think it all depends on content and competition of keywords. I don't think the blog type has anything to do with it.
