wordpress has some good qualities- i've used it for creating sites- but when it's coming down to blogging i would never switch to it from blogger!
blogger really is user friendlier and i find more reliable. not to mention the fact that you can't edit themes on wordpress without paying for it, what's up with that? maybe it's my own kink that i need to have a unique and pretty blog, while not caring about the plugins and extras wordpress has to offer.
in conlusion, you should always pick the provider carefully, considering your needs and vision for the future site.
