I guess it's useful to point out that "dofollow" is just a terms to refer to links that don't use a "nofollow" tag. They are still text links. So, indeed, the "dofollow" links would benefit you both as traffic source and as positions boosters, so they are better. more often than not, if you're using white-hat tactics, such as content-sharing you would be able to get proper dofollow links.
