I don't use adbright at all but as far as comparing wordpress to blogger, I use both.
Wordpress is going to very dependable because you are the one hosting it. It's very easy to manipulate and you can get help with it from tons of resources.
But Blogger is free. If you have finacial limitations it's perfect. It's not your own hosting so a lot of people are concerned about downtime. Since using blogger I personally have been very satisfied with their uptime.
I usually start with blogger for development of the site and then if I want to go further, I push it over to wordpress.
Good luck!
I started this blogger site this morning
www.thebestwife.com and as far as the eye can see, it's use-able.
