When I had a blog I used Wordpress. It has more functionality to personalize if you have someone that is building your site or you know how to build your site. I think people like blogger too as its more user friendly, but I never tried it.
WordPress is great and very easy to use. Buy the domain and you can get/customize a WordPress template pretty easily or have someone who is tech savvy set it up for you. Adding content is super easy though - if you can post on Facebook you can use it, lol.
