Differences between Blogger and WordPress

I searched for the differences of these two sites, and i clickex on one website that said some differences was that, in WordPress you are responsible for everything, you control and do everything and with blogger it's controlled by the site. WordPress has more different type of features when Blogger is mostly just blogging. Blogger is free and has a lot of spam. WordPress is something you download and yo ucan access it for free too. And posts from blogger can show up when searched in Google.
