Blogger v. Typepad

What's the difference between blogger and typepad?  Well, on the surface, zero cost and Google level infrastructure are 2 big advantages for blogger.  Of course, I'll still need to configure the custom URL (blog.instant-tech.com), but that looks like a manageable issue.

Typepad seems to have 'sexier' templates, but I've read some posts on the availability of the typepad servers.   

By the end of this week, I should have a good idea of whether we will use blogger or typepad.
