Which is the better ? Blogger vs Wordpress

Hello, We are members of a English speaking and learning club from 千曲市; Chikuma city, Nagano, Japan and now thinking which blog service is the better...blogger or wordpress. We once tried wordpress(cuz it was free...hehehe) .Yes, it was nice, there are many simple,cool and stylish templates that we can use free but we needed to pay some money for cusomize them... (we can't even change the font size !...sigh...) So... how about blogger ? Let's try !
