Wordpress has more flexibility than blogspot.
I use blogspot, which has worked until this week when I lost all my google juice. If you use blogspot, I will tell you that you should use the custom domain option from the start. It’s only $10 a year to maintain your custom domain name and believe it or not, some people will not give your blog the credit it deserves with at a blogspot address...The hosting is still free, and you can still use the blogspot software, it just doesn’t appear as a blogspot address. If you wait, and then switch to a custom domain, you’re going to have all kinds of problems. As I am having now.
Here is my blog, hosted by blogspot, but with a custom domain address
