Wordpress or Blogger?

Wordpress is definitely more customizable and has a hell of a lot of more options but Blogger is easy with my Google account which I use for Email, IM, Google Voice, Etc. So what should I use? I would love to actually get this blog to go somewhere, even though I stopped using it for quite some time. I also have an iPhone would like to easily edit and compose new blog posts on there. Blogger and Wordpress both can do that on the iPhone but even so. Wordpress also has plugins for iPhone versions of the web page which is nice.

What should I do?
