My vote goes to WordPress. I'm currently working on a new blog. I love how WordPress has all the free plug-ins. For example, you can install a plug-in that automatically generates and submits a sitemap to the major engines every time you make a new post.
Setting up the blog is just as easy as it is with blogger if you have a host with cpanel and they have many, many more templates to choose from. I also like how you can go into the WordPress control panel and they make it easy to find certain templates for custom edits. With Blogger you have one HUGE template with code for days.
With WordPress, if you want to edit your header, you open the header.php file. Or if you want to edit the footer, you open the footer.php file. And all template files are conveniently listed in the admin panel.
Blogger is probably slightly easier to setup but WordPress is best for the long-run. Glad I switched. I read your blog post, Lisa about your switch and that was the final straw that made me switch.

You were right!
