Is a Directory PR 5 link better than a Blog PR5? Is a home page link better than a deep link with same PR? Is there a link that is better than another and what about Cloud sites are they just as good? Sorry for all the ?s
Whether it is a directory PR5 or blog PR5 the most important is the traffic of the blog or directories that you can get from them. Where can you get higher traffic?
Directory will helps for your link popularity and Blog is for web traffic or with link popularity . Both are needed to increase traffic and for site popularity
if you get a link on the main page of the blog, then those are very valuable as each blog post will have your link.
I would pick a blog over a directory, and I would definitely pick a deep link within content over a homepage
