I have build two websites with CMS package. One is Mambo, the other is Wordpress. They all are good systems but with different features.

1: Wordpress can only be used on blog website. Mambo can be used on some other website.

2: It is very easy to install Wordpress. It only took me 5 minutes to install on the server without any problems. But Mambo took me 30 minutes or longer.

3: Wordpress has Chinese package and support Chinese very well. It is a little bit painful to use Mambor to build Chinese website, but works!

4: It is quit easy to change template in Wordpress system. You only need to unzip the template files and move them into the specified directory. Changing template in Mambo is a little bit complicated and difficult, you have to upload files from the backend and you will encounter problems most time.

Conclusion, if you only want to build a personal blog, I strongly recommend using Wordpress.
