wordpress or blogspot ?? which better ??

I want opinion about the popular blogging tool, which is wordpress and blogspot. Which one is better. Whether both of it has own advantages? I use wordpress (http://rmmict.wordpress.com) at the beginning of my involvement in blogging. Then i found that wordpress are very different than blogspot. Wordpress blog cant be like a blog that I use now using blogspot.(http://rmmict.blogspot.com).
In simple words, blogspot is cheerful than wordpress. For me, blogspot are more attractive, students will like the features that blogspot offered. .
