It depends on what kind of blog(s) you have and what your needs are. I started with blogger, but then they made their editor more difficult to use, so I switched to WordPress, but then they also made their editor more difficult to use, so I went back to Blogger, But then they made theirs even more difficult to use. They seem to be in a competition in that respect.
If you want to use pictures in your blog, I find the old unenhanced WordPress editor easier to use than the Blogger one (where you have to fiddle with HTML code to align pictures in the page) .
If you can afford it, you can also buy blogging software and pay a site to host a blog, and there are a zillion web hosting sites out there.
